Product Introduction

Overview

The AD8220ARMZ, produced by Analog Devices Inc., is a single-supply, JFET input instrumentation amplifier designed for high-performance, portable instrumentation applications. It is the first such amplifier available in an MSOP package, which significantly reduces the board area required compared to traditional SOIC packages. This amplifier is optimized for applications where low power consumption and high common-mode rejection ratio (CMRR) are crucial. It operates on a single supply from 4.5 V to 36 V or a dual supply from ±2.25 V to ±18 V, making it versatile for various system designs.
