Gain of buffer amplifier
WebA 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. WebCalculate R1 and R2 to obtain the gain you want. In this example, as the two resistors have the same value, the gain of the voltage divider is 0.5 Short the feedback resistor (0Ω). You want the amplifier to have a gain …
