Op Amp Differential Amplifier CalculatorDifferential amplifier calculator is an online engineering tool to help you determine the output voltage of a differential amplifier based on an operational amplifier. At the output of the differential amplifier the voltage (Vout) is equal to the difference between V1 and V2, multiplied by a constant:
To suppress the common-mode component, i.e. to amplify the difference between V1 and V2, it is necessary to observe the ratio of the resistors' values: R1 / R3 = R2 / R4 This calculator also displays the color coding and SMD codes for resistors used in the circuit.
