The Op-Amp Gain & Voltage Calculator is a powerful tool designed for analyzing and designing operational amplifier circuits. This op-amp calculator helps you find the output voltage (Vout), amplifier gain, and resistor values like R1 and R2. It works for both inverting and non-inverting configurations.
Simply enter the input voltage (Vin), supply voltages (Vcc and Vee), and any known resistor or gain values. If you leave R1 or R2 blank, the calculator will find the missing resistor. It does this based on the gain you want. Once all values are entered, click the “Calculate” button to view the output
Input Parameters
Tip: To calculate resistor values, set gain to desired and leave R1 or R2 blank.

OP AMP Resistor Calculator Overview
This tool helps calculate the output values of resistors R2, R3, and R4 in an inverting operational amplifier circuit. And the output properties are in KΩohms (kilo-ohms).

You should know the key parts of operational amplifier gain. These include R1 (KΩ), Vout, Vp, V2, and Vn. Make sure to understand these before doing the operational amplifier calculation.
Definition of Inverting Op Amp
The op amp inverting amplifier circuit is simple to build and construct, requiring only a few basic electrical components.
An inverting op amp is a type of operational amplifier circuit. It produces an output voltage that is the opposite of the input voltage. In other terms, it is 180 degrees out of phase.

FAQ
To use the calculator, enter the input voltage (Vin). Also, input the positive and negative supply voltages (Vcc and Vee). Finally, add the resistor values R1 and R2. You can also input a desired gain to auto-calculate missing resistor values.
Vout is calculated using the formula:
Vout = Vin × (–R2 / R1)
The result is limited by the power rails, so the final output will not exceed Vcc or drop below Vee.
Yes. If you enter the gain you want and either R1 or R2, the calculator will find the missing resistor for you.
The status shows whether the amplifier is working in the linear region or is saturated. If the output exceeds Vcc or goes below Vee, the status will indicate saturation.
