About this calculator
The Op-Amp Inverting Amplifier Gain Calculator is a simple and useful tool for calculating the gain of an Op-Amp Inverting Amplifier circuit.
This calculator uses the formula G = −Rf/Ri, where G is the gain, Rf is the output resistance, and Ri is the input resistance.
The Op-Amp Inverting Amplifier circuit is commonly used in amplifiers and it's essential to calculate the correct gain to avoid distortion or signal loss.
When using this calculator, keep in mind that the calculated gain is only an estimate and may vary depending on the specific characteristics of the Op-Amp used.
Frequently asked questions
