- In this video, the slew rate of an Op-Amp has been explained with solved examples.
What is Slew Rate:
It defines the maximum rate at which the output of the op-amp can change. (How fast the op-amp is able to respond)
Unit of Slew Rate: V/us
Different Op-Amp has different slew rate and the value of slew rate varies from 0.1 V/us to 1000 V/us.
So, depending on the application the op-amp with specific slew rate needs to be selected which prevents the distortion of the output signal.
Causes of Slew Rate in Op-Amp:
The internal compensation capacitor in the Op-Amp is the main cause of slew rate in every Op-Amp.
The value of Slew rate depends on the value of this internal compensation capacitor and the charging or driving current.
Power Bandwidth of the Op-Amp:
The maximum frequency (for large signals) up to which there will not be any distortion in the output is known as the Power bandwidth of an op-amp.
This power bandwidth of the op-amp (slew rate limited maximum frequency ) is defined for the large signal (in volts), while the unity gain-bandwidth product is defined for the small signals (in mV).
If the input frequency is more than this maximum frequency, then the output signal will start getting distorted. And this kind of distortion in output is known as the slew rate induced distortion.
