Op-Amp Gain Calculator

Operational amplifiers (Op-Amps) are widely used to amplify signals. This calculator helps you compute the voltage gain (A_v) for both inverting and non-inverting amplifier configurations, based on resistor values.

Input resistor:

Feedback resistor:

Mode:

The formula is:

Inverting amplifier

\[ A_v = - \frac{R_f}{R_{in}} \]

Non-inverting amplifier

\[ A_v = 1 + \frac{R_f}{R_{in}} \]

Where:

A_v = Voltage gain
R_f = Feedback resistor (Ω)
R_in = Input resistor (Ω)
