This Op-Amp Calculator will give Result Gain and Output Amplitude with respect to the Input Resistor (R1), Feedback Resistor (R2) and Input Amplitude (Vin). Just enter the Input values and get result by pressing calculate button.
Op-Amp Calculator
Inverting
Non-Inverting
Formulas used by this calculator, Vout = AVin
The output Voltage (Vout) is equal to the product of Amplifier gain (A) and the input Voltage (Vin).
Inverting Amplifier
To calculate gain for Inverting Amplifier use,
Gain (A) = R2/R1
Gain (A) = Rf/Rin
Output Amplitude = A*Vin
Here the calculator takes absolute value of gain and removes negative sign, that is typical for Inverting Amplifier.
Non Inverting Amplifier
To Calculate Gain for Non Inverting amplifier use,
Gain (A) = 1+(R2/R1)
Gain (A) = 1+(Rf/Rin)
Output Amplitude = A*Vin
