Op Amp Gain Calculator

With a non-inverting opamp, the input voltage signal is applied directly to the non-inverting (+) input terminal which means that the output gain of the amplifier becomes "Positive" in value, in contrast to the "Inverting" opamp where the output voltage changes in an opposite direction to the input voltage.

The calculator is based on the formulas:

Gain = (R1 + R2)/R2 and Gain = R1/R2

Enter the values of R1 and R2 and click Calculate.

R1 : Ω (ohms)
R2 : Ω (ohms)
