I watched this video 2 years ago and didn’t have a clue what was going on. I rewatched this video today and understood everything just fine. I don’t have a college education in electrical engineering. I just learn from RUclips and experimenting. Don’t give up!
Honestly as someone who knows about op-amps, I suggest you go slower. You rushed through so quickly! I KNOW the concept and found it difficult to catch up to your speed.
I know circuits, love your videos, and just watched this for a second time. This is a ridiculous whirlwind of great information but delivered at an absurd rate. Please continue the great work but SLOW DOWN for the basics videos!
Man you seem to know what your doing, just found you not long ago but your so fast in your explaining how things work that i can never fully understand what your trying to say. If these videos are basics for beginners then im sure so many more people would love to watch these videos, cause they are knowledgable and you do cover alot of things people need and love to know. Your great at what u do, so if u could take the time and explain stuff more slow, and thoroughly im sure im not the only one who would love and appreciate what u do even more. Thanks keep doing great work.
What a wonderful oscilloscope! I am an old technician, from the days of vacuum tubes, back in 1960. My "most advanced " scope was an Eico 460 - I enjoy your videos.
I love your videos. I’m an old, rusty, electronics technician (two year bachelors course at An electronics “college” when they still taught basic principles but that was in the eighties) but for me this went so fast. I got about 1/3 of it. I do thank you for showing me very clearly I need to go back to school, go back and read my electronic principles books from school again.
It's difficult to understand his videos because he just slams facts at you but doesn't elaborate. The only way you'd follow this video is if you knew about op-amps before hand, in which case, why would you be here?
@eman khaled Even after having learnt it before, I don't really understand the contents here, because its hard to imagine the whole circuit. There are lots of stuff going on in an op-map circuit to satisfy the mathematics equation by using electrical components.
this is the first video of great scott where I didn't understand even half of what op amp is. And I'm a final year student of Electrical Engineering Bachelor degree. Wow Im so dumb dude
Excellent work there. I've used opamps so many times I could probably make an amp while sleeping, now class D and T are so fun to build (love building them!).
I'm not good understanding listened english and even sometimes written english, and I'm able to read and follow the subtitles without problem... Also is youtube, you're able to pause and listen again what you need.
Mr. Chow, my electronics instructor used to say, "DC is the horse and AC is the rider". BTW, I loved the op amps in college and built some cool circuits in the lab. I became intrigued with op amps when I found a book about op amps when I visited an old Heath Kit store in the 70's.
Honestly I don't have enough time to watch the video but I love your videos so much that I put like , comment then went back to my work I love you , keep the great work up
I love your videos,They are awesome.My TV has wifi and I stream your videos to take a break or while killing some snacks.Your videos are better than cable.
I love your channel! It never fails. Whenever I want to look something up to either see if it’s the right component for the task, or to learn how it works, you’ve always got great videos that help me progress quickly and very rarely slow down unless I want to dive deeper. Thank you!!!
Great Video as always: I like that you go a bit fast to have all the info in a few minutes. I can go back to the part I need to clarify again. Keep up the good work! :)
I have been dealing with general electronics, electro/mechanical repair since the late 70's and have an aptitude for this without any formal training. Like the 555 timer video, this one and others I have watched, you go so fast without explaining that If one does not already know what you are talking about it all flies right over the head. Example, here are some other comments... Hani Al Jamal 4 years ago Who else enjoys watching GreatScott's videos but barely understands anything? 😂 Paul Sampson 1 year ago It's good review at the very least Paul is an example of someone who has had training and therefore can understand without explanation.
Didn't know how they work at start and still no idea after watching it, you are presenting it as if you are explaining it to a professor and not to a beginner.
Setting DC offset to op amp: Set the desired audio signal gain you need to the inverting terminal of OP AMP (-). In non-inverting terminal (+) connect a voltage divider using, lets say, two 100k resisters. Connect one 100K resistor terminal to positive voltage supply and the other terminal to the non-inverting terminal (+) of OP AMP. Next connect the second 100K resistor one terminal to Ground (0 volt) and the other terminal to the non-inverting terminal (+) of OP AMP. By doing so, you have created a DC offset that utilizes the whole range of your positive supply voltage from peak to peak in which DC offset is located at the middle of your positive supply voltage. Just make sure your calculated voltage gain does not exceed the positive supply voltage (preferably 1 volt lesser than your positive supply voltage to avoid clipping if you need to amplify the signal that much). After that, you will get an amplified AC signal on a DC offset. To remove the DC offset before connecting to a speaker, use decoupling capacitor.
this electronic basics is a bit quick and advanced for me, i get confused qucikly with the terminology especially if they are so quick in succession without explaination haha, feels like a basic video if you already know what an op amp is
+Azagro I knew you would say that, sorry for any mistone catch of what I'm saying. Let me tell you, putting 25 minute video almost no cut, just explaining what an op-amps is, no edit, no struggle to make the video looks better, is not how you explain something on RUclips. He's almost dull, his video is low at "Point per time" score, in another word, 'Very low efficiency". He's not that type of the guy who plans His video more than 24 hour, look how people explains it in books and another videos, then wrapping it, try to record it again and again until He got maximum result, then make the video great to see. Ask people if they like and understand it, then wait for another few hours to see if His video got any mistakes, then upload it... In another word, a perfectionist. Then goes this, His attitude, His obsessing with yellow things, His way of mocking bad products, is really, inapropriate for a teacher to do, coz he's not. If you want to look at great channels, go to channels like DIY Perks, Collin Cunningham, or Michel van Biezen's video. DIY Perks is a very good example of how premium channels should look like, He got a very great passion, and sense of beauty for His channel, even though sometimes His project is not very useful to use, He wants His channel looks great, so He buy a very good microphone before He barely got money from His channel. Michel's video is what you should call " almost flawless explanation". His videos are short, easy to understand, and easy to imagine. Because He's a teacher. Though the video is not really eye appealing, His explanation was beautiful. GreatScott's channel however, is channel made by a very passionate electronic engineer, He wants people to understand, but there's a language and culture barrier. That what makes His videos too fast, and hard to imagine. You should watch and learn a lot of light stuff before you can actually understand His wideos (Videos). Collin's video? They're good af, for a total beginner. He's like GreatScott with no barrier but crew, friends, and idea. Get it now? Anyway every channel has their own cons and pros, and not everybody can make great channel.
your timing is spot on the other night i was looking into building a 12 channel EQ and that little tid-bit of ICs with 4 OpAmps makes my layout so so much easier back to EasyEDA (thanks for that vid too) I want to build a head unit with only a dock for my nexus that runs on BT. Behind the dock would be 24x 20mm linear slide pots
some time ago i'll probabbly jump this video in th part of types of opamps... but since i have those lessons on university, i can see what i learned being usefull and have some sense! amazing Scott
I would like to see, as a future project, a very simple audio mixer that can take 5 inputs and feed my speakers from all 5. I do not need level controls or any thing like that as each has its own volume. Cool project! Love them all!
There were Babani Publishing books about this subject. Operational Amplifier User's Handbook ref. BP335 and Circuit Sourcebook 1 ref.BP321 are 2 books that I know in the Babani Publishing series. Others are How to Use OpAmps ref. BP88 and Preamplifier and Filter Circuits ref.BP309.
Thank you for the explanation. The hint with the 10 kOhm resistor between "input +" and GND made my day. I don´t exactly understood its neccessarity at this position but it worked (All what matters for now).
+DanielsLPecke I don't understand why so many people find it appealing to stand on top of a box and say that they don't understand something. I'm genuinely curious - do you mean that you would like him to make even simpler videos that you can understand, or are you proud of your ignorance. I'm not trying to be mean here, I just don't understand this behavior and I've been curious about it lately.
***** I am asking whether he is calling for simpler/more basic videos, or what? It seems like there are often a bunch of people commenting "Haha, I don't understand anything you said LOL LOL." They usually seem like they're more in the line of parading ignorance than asking for more basic help.
Be advised when you look at the absolute characteristics. I used a LT1078 which said supply is +-22. I gave it +12 and -12 and barbecued the damn thing. On the LM358 it does say +-16 BUT it also says single supply can go up to +32 meaning it can certainly withstand a rail to rail swing of 24 volts, which was what the +-12 gives it. According to paper, the LT1078 should have as well, but it didn't.
You forgot to mention another key fact or should I say Rule #2. When used with negative feedback a Opamp's input never draws current but draws current from the voltage input. Another oldie but goodie of a Opamp is the LM741. It has a few advantages such as overload protection. When building a circuit that requires a Opamp and after you have figured out for requirements then start reading up data sheets and compare between the LM358, LM741 and the LM10. If anything else I would look at the LM part list on Wikipedia.
Nice Video but WAY TO FAST. I still gave you a thumbs up for all the good information. I felt like I was in speed electronic training. Thanks for sharing. Best Wishes n Blessings. Keith
I subscribed to your channel after watching this video. I finally feel like I understand the basics of Op-Amps. The derivation for the inverting op-amp formula in particular made it click for me. Thanks!
This is pretty clear and digestible as a refresher but it might be serviceable to slow the pace of the video down if it's directed towards complete beginners.
4:25 Can anyone explain to me what does connecting the plus input to a DC offset achive? And/or what would happen if the plus input was simply connected to ground instead? Thx in advanced.
I really like how all of your videos are edited. How do you approach pre-production? Do you write a script first and then film, or film and construct a script from your footage? How often do you have to go back and film extra bits you discover you had missed? How much of your original footage usually makes it into a final video? Sorry for the slightly unrelated questions! Please keep videos coming!
+GreatScott! Could you please do a video on batteries, c rating, charging, etc? Like for you basics section? And maybe a little discourse on batteries vs ultra-capacitors as far as functionality is concerned?
I really enjoy your electronics videos and I'm experimenting with an opamp, trying to amplify a microphone. I can follow most of whats in this video but there is a part that I'm confused about. In the first opamp example, you say "A 10k-ohm pulldown resistor to set the reference voltage". I do not understand the reference voltage part and how it is related to using a pulldown resistor.
Your videos are very good just one thing would make them great … for future Videos it would be good to implement some > _delay_ms(500); < between the scene change cuts … it makes then more comfortable to pause at the right spot. Greetings from Switzerland and good continue for the future Patrick
I love GS videos, too. I like that they are straight to the point and packed with excellent information. The key word being "packed"! I agree with you that a little "delay(1000);' would help out a lot. Not only in between scenes, but sometimes the information he's jotting down goes by so fast, it's hard just to pause at the right time so I can "analogWrite(PAPER1, copyGSnotes);"! :D That being said, this is his channel and his product(videos) are of his design - Given the choice of 'take it or leave it', I'll take it! Thanks for the videos +GreatScott! and keep up the good work !
I like how your videos are simple and informative, I did my own research on OpAmps quite a lot before but didn't understand what you explained in a couple seconds. I guess I can start working on my 12AX7/D-class guitar amp again, thank to you
I watched this video 2 years ago and didn’t have a clue what was going on. I rewatched this video today and understood everything just fine. I don’t have a college education in electrical engineering. I just learn from RUclips and experimenting. Don’t give up!
OpAmp = Overpowered amplifier
Yes same with me, i just study electronic using youtube
Thanks for this comment, I have no idea what's going on. Trying to build a amplifier and I feel like I have a long way to go.
Its gonna take me two years !?
Thankyou for motivating
Honestly as someone who knows about op-amps, I suggest you go slower. You rushed through so quickly! I KNOW the concept and found it difficult to catch up to your speed.
Watch it multiple times or pause the video inbetween.
his vids are grea but way to fast.
Nobody would watch if the video lasts 15min...
xgenesys Unless the video is from EEVBlog.
Just take the bloody criticism and slow down.
I know circuits, love your videos, and just watched this for a second time. This is a ridiculous whirlwind of great information but delivered at an absurd rate. Please continue the great work but SLOW DOWN for the basics videos!
Man you seem to know what your doing, just found you not long ago but your so fast in your explaining how things work that i can never fully understand what your trying to say.

For anyone wanting a deeper dive into opamps i can recommend EEVBlogs video on that topic from a few years ago.

It's good review at the very least
Very good point

🙋🏻♀️🤣🤣
He is splurging too much info too fast. Both audible and visual (formulas) which causes my brain to freeze thoughout the whole video.
Basics you say?
@eman khaled Even after having learnt it before, I don't really understand the contents here, because its hard to imagine the whole circuit. There are lots of stuff going on in an op-map circuit to satisfy the mathematics equation by using electrical components.
This video did a great job of explaining why I don't understand op amps....
this is the first video of great scott where I didn't understand even half of what op amp is. And I'm a final year student of Electrical Engineering Bachelor degree. Wow Im so dumb dude
Excellent work there. I've used opamps so many times I could probably make an amp while sleeping, now class D and T are so fun to build (love building them!).
Your explanations are tooooooo......fast!! Didn't get anything from your videos
Nothing at all. Just like having a rapper as a lecturer
called a pause button or just slow down the video
Two solutions. First, slow down the video.
Second, watch the video more than once.
You should listen in a quite place
I'm not good understanding listened english and even sometimes written english, and I'm able to read and follow the subtitles without problem... Also is youtube, you're able to pause and listen again what you need.

+mohamad bilal (Speed King) Thanks mate ;-)
+GreatScott! Welcome
I love your videos,They are awesome.My TV has wifi and I stream your videos to take a break or while killing some snacks.Your videos are better than cable.
That was refreshing !!! I grew up with these kiddies in the 70s, still am in love. Now go to JFET opamps and those goodies. THANKS !
I love your channel!
It never fails. Whenever I want to look something up to either see if it’s the right component for the task, or to learn how it works, you’ve always got great videos that help me progress quickly and very rarely slow down unless I want to dive deeper.
Thank you!!!
I love this channel,he teach in so much easy way.
You are GREAT! Greetings from Argentina. :)
Set play speed = 0.75 will make things easier to follow
3:30 FINALLY someone told me about this
Great Video as always: I like that you go a bit fast to have all the info in a few minutes. I can go back to the part I need to clarify again. Keep up the good work! :)

Paul Sampson 1 year ago
It's good review at the very least
Paul is an example of someone who has had training and therefore can understand without explanation.
This is a great video. I am an electrical engineering student, and this is a simple explanation that helps me out.
very good idea I am a loyal fan of your channel .. always successful
Most of the people are Technicians. There are very few Engineers like you. Thanks
Ashok. Bangalore
Really great
it just clicked thanks to ur vid, thanks a lot !
I learned from you a lot more than i did in school thank you thank you
More electronic basic please!!
I like how he says "let's get started" exactly the same every video! :)
How serendipitous! I selected this one hoping for discussion of microphone amplification.
Hey your videos are great, in fact your the first place I go to for explanations on components, keep them coming!!
Diagram going to fast
Press pause
Awesome video! Go to the settings icon (looks like a gear) and bump the speed down to 0.5.
slowdown the video
PDF diagrams!
Watch video in 0.5x
Love your videos, great job using correct terminology!
Didn't know how they work at start and still no idea after watching it, you are presenting it as if you are explaining it to a professor and not to a beginner.
Another awesome video scott.
thanks! i have recently received exactly 100 LM358 OP Amps (which only costed $4 lmao), and now i actually know how to use them.
Had to stop few times while watching videos to google something, but this video is golden :)
Very clever explanation. Thanks.
Setting DC offset to op amp:
Set the desired audio signal gain you need to the inverting terminal
of OP AMP (-).
In non-inverting terminal (+) connect a voltage divider using, lets
say, two 100k resisters. Connect one 100K resistor terminal to positive
voltage supply and the other terminal to the non-inverting terminal (+)
of OP AMP. Next connect the second 100K resistor one terminal to Ground
(0 volt) and the other terminal to the non-inverting terminal (+) of OP
AMP.
By doing so, you have created a DC offset that utilizes the whole range of
your positive supply voltage from peak to peak in which DC offset is
located at the middle of your positive supply voltage.
Just make sure your calculated voltage gain does not exceed the positive
supply voltage (preferably 1 volt lesser than your positive supply
voltage to avoid clipping if you need to amplify the signal that much).
After that, you will get an amplified AC signal on a DC offset. To
remove the DC offset before connecting to a speaker, use decoupling
capacitor.
this vid is really helpful ,keep continuing this electronic s basics
this electronic basics is a bit quick and advanced for me, i get confused qucikly with the terminology especially if they are so quick in succession without explaination haha, feels like a basic video if you already know what an op amp is
I have no idea what he's doing
I have no idea what he's talking about
but it's interesting
and as far as I can tell he's doing it very well
..
I think
I like how Scott is casually using a 14k Oscilloscope. Lol, I hope I can get one some day.
Great videos, kudos to you man, you deserve it.
Great Scott you are truly great
I didn't understand a word of this after hooking up the first ground and 12V but your voice is cool anyway. Rock on dude.
I would like to say I get it, but I don't get jack shit
+Don Grille Try watching the OP-Amp tutorial from the EEVBlog, more indepth.
+Azagro
Sorry, but eevBlog is pain in the ass, the guy, and the channel..
I would suggest buy a book.

Sorry for the long comment..
Took me 40 minute to finish.. :) (See what I did there?)
your timing is spot on the other night i was looking into building a 12 channel EQ and that little tid-bit of ICs with 4 OpAmps makes my layout so so much easier back to EasyEDA (thanks for that vid too) I want to build a head unit with only a dock for my nexus that runs on BT. Behind the dock would be 24x 20mm linear slide pots
Great Scott you knowledge is great
Perfectly paced video. Thank you.
This is the first video of the series that skims way too fast over the details of such a large topic. Please make a longer video on opAmps! :)
some time ago i'll probabbly jump this video in th part of types of opamps... but since i have those lessons on university, i can see what i learned being usefull and have some sense! amazing Scott

What do I need to learn to be you? I love electronics but I can't work. I admire you
Great video bro 👋
Thank you for the explanation. The hint with the 10 kOhm resistor between "input +" and GND made my day. I don´t exactly understood its neccessarity at this position but it worked (All what matters for now).
no idea what you are talking about but i like it
i dont understand a single word
+DanielsLPecke Do you not understand english?
not THAT english :(
+DanielsLPecke I don't understand why so many people find it appealing to stand on top of a box and say that they don't understand something.

Good work as always.
I built an DC - AC power inverter, the control circuit was built mostly with op amps, it was a pain in the arse but it was fun
You forgot to mention another key fact or should I say Rule #2. When used with negative feedback a Opamp's input never draws current but draws current from the voltage input.

I agree.. I would like to see this same content, but in about 30 minutes of explanation!
I like your way of speaking especially the "Let's get started" 😂😂😂
I subscribed to your channel after watching this video. I finally feel like I understand the basics of Op-Amps. The derivation for the inverting op-amp formula in particular made it click for me. Thanks!
This is pretty clear and digestible as a refresher but it might be serviceable to slow the pace of the video down if it's directed towards complete beginners.
Very good video!
You should do a video on a diy solder pot. Those are stupidly useful.
Great Video very well described!
Thanks a lot man it really helps
I wish to one day fully understand the electronics behind OpAmps
Loved this one.
This video is just awesome
4:25 Can anyone explain to me what does connecting the plus input to a DC offset achive? And/or what would happen if the plus input was simply connected to ground instead? Thx in advanced.
I really like how all of your videos are edited. How do you approach pre-production? Do you write a script first and then film, or film and construct a script from your footage? How often do you have to go back and film extra bits you discover you had missed? How much of your original footage usually makes it into a final video?
Sorry for the slightly unrelated questions! Please keep videos coming!
I will answer this question in my Q&A&C show
Thanks!
Excellent tutorial series. thumbs up ;)
Please create a playlist of this Electronics basics. 🙏🙏🙏
+Monochrome 680 There is already one
+GreatScott! oh my mistake, i didn't search correctly. Sorry 😉
@@greatscottlab Beginners don't understand what u say. Plz explain tings slower and more Understandable
Why did you use that 10K pull-down resistor in the non-inverting amplifier?
In other words, what does it mean to set the reference voltage?
Because the voltage at inverting and non-inverting terminal should be equal.
+GreatScott! Could you please do a video on batteries, c rating, charging, etc? Like for you basics section? And maybe a little discourse on batteries vs ultra-capacitors as far as functionality is concerned?
Sure. I put it on my to do list.
GreatScott! Thank you :D Always excited to see what you've put up! I love this channel
Fantastic Video Dude. Really Helpful. It would be good to see some more Videos about Op Amps. Keep up the great work. Nick.
Yeah finally!
Can you make a video about 555 ? Thanks.
+Parker John oh yeah, the classic and loved by everyone IC555. totally agree
a 555 Video would realy be great!
h made it
Scott, you use the word 'constellation' but I think you mean 'application', just FYI - love your content, thank you.
Every time he says that, my minds replaces it with "universe" like... "this works this way anywhere in this universe"
You are a master!
Thanks Scott.
I really enjoy your electronics videos and I'm experimenting with an opamp, trying to amplify a microphone. I can follow most of whats in this video but there is a part that I'm confused about.
In the first opamp example, you say "A 10k-ohm pulldown resistor to set the reference voltage". I do not understand the reference voltage part and how it is related to using a pulldown resistor.
Your videos are very good just one thing would make them great … for future Videos it would be good to implement some > _delay_ms(500); < between the scene change cuts … it makes then more comfortable to pause at the right spot.
Greetings from Switzerland and good continue for the future

I love GS videos, too. I like that they are straight to the point and packed with excellent information. The key word being "packed"! I agree with you that a little "delay(1000);' would help out a lot. Not only in between scenes, but sometimes the information he's jotting down goes by so fast, it's hard just to pause at the right time so I can "analogWrite(PAPER1, copyGSnotes);"! :D
That being said, this is his channel and his product(videos) are of his design - Given the choice of 'take it or leave it', I'll take it!
Thanks for the videos +GreatScott! and keep up the good work !
I like how your videos are simple and informative, I did my own research on OpAmps quite a lot before but didn't understand what you explained in a couple seconds.
I guess I can start working on my 12AX7/D-class guitar amp again, thank to you
Thanks for this Video, really nice, just like allways. I hope that I can now understand op Amps. I will try tomorrow.
Good video.
