LT1996IMS#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1996IMS#PBF is a precision, micropower gain-selectable amplifier from Analog Devices Inc. It integrates an operational amplifier with eight internal precision resistors to provide selectable gains without external components. The device supports difference, inverting, and noninverting configurations. Key electrical parameters include a maximum input offset voltage of 50µV, a gain bandwidth product of 560kHz, and a supply current of 100µA at 5V. It operates on a wide supply range from single 2.7V to split ±18V. The output swings rail-to-rail within 40mV of the rails. Common mode rejection ratio exceeds 80dB in difference amplifier mode.
