The differential gain is _____________?
Correct answer: A. very high
- A. very high
- B. very low
- C. dependent on input voltage
- D. about 100
Explanation
An op-amp's differential gain is designed to be very large so even a small voltage difference between its inputs can produce a substantial output. The common-mode gain, in contrast, should be very low.
