Product Introduction

Overview

The AD8657ARMZ is a dual micropower, precision, rail-to-rail input/output operational amplifier produced by Analog Devices Inc. This amplifier is optimized for low power consumption and a wide operating supply voltage range, making it suitable for a variety of applications. It features a low offset voltage, very low input bias current, and high immunity to electromagnetic interference. The AD8657ARMZ operates from a single supply of 2.7V to 18V or a dual supply of ±1.35V to ±9V, with a typical quiescent supply current of 18 μA at 18V.
