What is the Frequency Response of an OP-Amp?

Answers

The operating frequency has a significant effect on the operation of an OP-amp. The following are the important points regarding the frequency response of an OP-amp:
(i) The maximum operating frequency of an OP-amp is given by;

(ii) Thus, the peak output voltage limits the maximum operating frequency.
(iii) When the maximum operating frequency of an OP-amp is exceeded, the result is a distorted output waveform.
(iv) Increasing the operating frequency of an OP-amp beyond a certain point will:
(a) Decrease the maximum output voltage swing.
(b) Decrease the open-loop voltage gain.
(c) Decrease the input impedance.
(d) Increase the output impedance.
