LTC6081 Two Op Amp Instrumentation Amplifier

Two Op Amp Instrumentation Amplifier

Instrumentation amplifiers present a high input impedance to a differential input signal source and provide a single ended output. This circuit uses the non-inverting inputs of each amplifier of the dual LTC6081 for the differential input terminals. The gain is set with external resistors to over 1000. A CMRR trim cancels the effects of resistor value tolerances that may create differential signals from input common mode voltage changes.
