AD8618ARZ-REEL7

Instrumentation, Op Amps, Buffer Amps Overview

The AD8618ARZ-REEL7 is a quad, rail-to-rail input and output, single-supply CMOS operational amplifier from Analog Devices. It features very low offset voltage (23 µV typical), wide signal bandwidth (>20 MHz), and low noise (8 nV/√Hz). The device operates on a single supply of 2.7 V to 5 V, consumes 1.7 mA per amplifier, and provides high output current drive capability of 150 mA. It utilizes a patented trimming technique for superior precision without laser trimming.
