Question

If f = 20 kHz, what is the maximum value of Vi before the output distorts?

(a) 0.397 V

(b) 0.795 V

(c) 1.192 V

(d) 1.590 V

This question was addressed to me in an online interview.

Query is from Large Signal Operations on operational Amplifiers in section Operational Amplifiers of Electronic Devices & Circuits

Answer 1

The correct answer is (b) 0.795 V

To explain I would say: V0 = 10Vi

2πf V0 = SR = 20πf Vi, here f is 20 kHz, SR is 1  V/µs. Hence the value of Vi is 0.795 V.
