Analogue, Mixed Signal, LSI
Linear Technology's LT1789-1 is a micropower instrumentation amplifier that features superior DC performance while drawing only 95 µA supply current maximum. Optimised for low voltage single supply operation, it maintains precision performance from 2,2 V to 36 V. It has low input offset voltage of 100 µV max, low input offset drift of less than 0,5 mV/°C, and a high power supply rejection and common mode rejection ratio of 100 dB min. Gain error (G=10) is 0,25% max. The device's inputs that common-mode to ground, and its output that swings rail-to-rail, maximises dynamic range in low voltage applications. Voltage noise density at 100 Hz is 48 nV/rt.Hz. Available in 8-pin surface mount package, the LT1789-1 is fully specified over -40 to 85°C.
