Differential amplifiers are used in______________?
Correct answer: A. Instrumentation amplifiers
- A. Instrumentation amplifiers
- B. Voltage followers
- C. Voltage regulators
- D. Buffers
Explanation
An instrumentation amplifier is built from differential-amplifier stages so it can amplify the voltage difference between two inputs while rejecting common-mode signals. Voltage followers and buffers are usually single-stage applications of op-amps.
