Precision difference amplifier measures differential voltages in the presence of common-mode input voltage up to 110 V above the negative supply. The device supports a 2.7 V to 20 V supply range, 120 dB minimum CMRR, and 0.45 mA typical quiescent current. Four gain variants cover 0.2 V/V to 1 V/V, with an enable pin that places the output in a high-impedance state when disabled. The 8-pin SOT-23-THN package supports operation over a -55 °C to 125 °C temperature range.
