Hi James, can you explain the reason why you picked this combination of values for R&C? I am trying to understand how to derive the design of a low pass filter for these types of IC sensors - I cant get my head around what I should be using as my cut-off frequency?
Hey Sean, I picked the values for the RC confirmation such that it would make 1 (simple on the maths). How are you getting on with frequency response now?
@@DrJamesEPickering Clearly, this is a frequency response of a lowpass filter. In your circuit you are only dealing with a DC voltage (the supply VCC ) so I don't see the advantage of including a capacitor here.If i am totally wrong can you please explained.

Sir is the output of temperature sensor signal in this case an AC or DC?
The power source used here is DC.
