Precision monolithic instrumentation amplifier provides differential inputs and an accurately programmable gain relationship. Gain is set with two external resistors over a 0.1 to 1000 range, with high input impedance and high common-mode rejection. The amplifier operates from ±5 V to ±18 V supplies and delivers a rated ±10 V output at ±10 mA. Inputs include protection for overvoltage up to ±15 V beyond the supply rails and 30 V differential.
