An internal op-amp inverter allows at least one of these levels to be , .-0.3V to 40V A voltage follower (also called a unity-gain amplifier, a buffer amplifier, and an isolation amplifier) is a op-amp circuit which has a voltage gain of 1. This means that the op amp does not provide any amplification to the signal.
