What is a Voltage Follower?
A
voltage follower
(also called a unity-gain amplifier, a buffer amplifier, and an isolation amplifier) is an
op-amp circuit which has a voltage gain of 1.
This means that the op amp does not provide any amplification to the signal. The reason it is called a
voltage follower is because the output voltage directly follows the input voltage, meaning the output
voltage is the same as the input voltage. Thus, for example, if 10V goes into the op amp as input, 10V
comes out as output. A voltage follower acts as a buffer, providing no amplification or attenuation to
the signal.
