Product Introduction

Overview

The AD822ARMZ is a dual precision, low power FET input operational amplifier (op amp) produced by Analog Devices Inc. This component is designed for general-purpose amplifier applications and extends its utility to precision instrumentation systems, medical equipment, and automotive applications. It operates from a single supply of 5 V to 30 V or from dual supplies of ±2.5 V to ±15 V, offering true single-supply capability with an input voltage range that extends below the negative rail. This feature allows the AD822 to accommodate input signals below ground while in single-supply mode.
