Single Supply Strain Gauge Amplifier

A dual CMOS amplifier with low supply voltage operation and rail to rail input and output performance makes single supply operation easy. This circuit provides a gain of 1001 to the small differential input signal from a low voltage strain gauge bridge transducer. High input impedance allows for high valued input resistors to minimize loading on the bridge network.

Tools & Simulations
