Inverting Op-Amp Resistor Calculator

Inverting Op AMP Resistor Calculator is a great op amp calculation tool for the operational amplifier inverting circuit. With this inverting amplifier calculator, you are able to calculate the resistance of R2, R3 and R4 resistor with ease. Because you just enter the input parameters of inverting op amp gain, the output voltage(Vout), R1 Resistance, the values of V1, V2, Vp and Vn, and then click the "Calculate" button.

Inverting Op-Amp Overview

An inverting operational amplifier (op-amp) not only amplifies the input signal but also reverses its polarity. This calculator helps determine the values of resistors R2, R3, and R4 based on the provided parameters. The output values are expressed in kilo-ohms (kΩ).

Inverting VS Non inverting op amp

The operational amplifier can be set up as either a non-inverting amplifier or an inverting amplifier. The diagrams of these two amplifier configurations are displayed below:

For inverting op-amp:

For non-inverting op-amp:

Any of these amplifier configurations can be cascaded to achieve higher gain. By cascading two inverting op-amps, the signal can also be returned to its original polarity.
