Differential Op-Amp Resistor Calculator

This calculator determines the necessary resistor values based on input and output voltages. Note this only works when VIN2 is a constant DC voltage. Also, this is an inverting configuration so the Minimum input voltage corresponds to the maximum output voltage. and vice versa.

Differential Op-Amp Circuit Schematic

INPUT VALUES		RESISTOR VALUES		OUTPUT VALUE (Based on Resistor and Voltage inputs)
VIN1 (Minimum Voltage)		R1		VIN1
VIN1 (Maximum Voltage)		R2		VIN2
VOut (Minimum Voltage)		R3
VOut (Maximum Voltage)		R4		VOut
Input Voltage VIN2		Negative Terminal Voltage
