OP291GSZ-REEL7

Instrumentation, Op Amps, Buffer Amps Overview

The OP291GSZ-REEL7 is a dual-channel, micropower, single-supply operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities, allowing operation with supply voltages ranging from 2.7 V to 12 V. Key electrical specifications include a gain-bandwidth product of 3 MHz, a slew rate of 0.5 V/µs, and an input offset voltage of 80 µV. The device draws a total supply current of 260 µA for both channels and provides an output current of 16 mA per channel. It is housed in an 8-SOIC package and operates within a temperature range of -40°C to 125°C.
