Voltage Follower OP Amplifier: What is it? (Gain & Circuit Diagram)
Feb 24, 2012 · A voltage follower (also known as a buffer amplifier, unity-gain amplifier, or isolation amplifier) is an op-amp circuit whose output voltage is equal to the input voltage (it “follows” the input voltage). Hence a voltage follower op-amp does not amplify the input signal and has a voltage gain of 1.
