Instrumentation Amplifier Easy

Circuit to amplify the difference of two voltages.

Designed for:
Output: V_out = (V_in2 - V_in1) * 10
Gain: A = 10

Resistors can be varied to adjust gain. Two opposite resistors should always have the same value to get a reasonable result. Usually, gain is set by the lonely resistor in the middle of the first stage.

Last OpAmp input terminals must be swapped, to not make it a schmitt trigger. Take it easy.
