Op-Amp Gain Calculator

Find the gain of an inverting or non-inverting op-amp.

Calculated Output

Gain (V/V) 11

Formula: Non-inverting: 1 + Rf/Rin; Inverting: -Rf/Rin

Step-by-Step Breakdown

1. Values used:

2. Feedback resistor Rf = 10,000 ohm

3. Input resistor Rin = 1,000 ohm

5. Gain = 11V/V

Did this calculator solve your problem today?

The math behind it

Non-inverting gain = 1 + Rf/Rin. Inverting gain = -Rf/Rin (the minus flips the signal).

Rf 10k, Rin 1k non-inverting gives a gain of 11.

Why is inverting gain negative?

The output is 180 degrees out of phase with the input.
