1 Overview

The INA1H94-SP is a radiation-hardened precision unity-gain difference amplifier with a very high input common-mode voltage range. The INA1H94-SP is a single, monolithic device that consists of a precision op amp and an integrated thin-film resistor network. The INA1H94-SP can accurately measure small differential voltages in the presence of common-mode signals up to ±150V. In many applications where galvanic isolation is not required, the INA1H94-SP can replace isolation amplifiers. The excellent 0.0005% typical nonlinearity, high common mode, and 500kHz bandwidth of the INA1H94-SP makes for a compelling sensor readout device. This device runs on a single 4V to 18V supply or dual ±2.V to ±9V supplies.
