Product Introduction

Overview

The AD8221ARMZ is a precision instrumentation amplifier designed by Analog Devices Inc. This device is known for its high performance and versatility, making it an excellent choice for various applications that demand high DC performance and low noise.

The AD8221ARMZ operates with a wide power supply range of ±2.3 V to ±18 V and is specified over the industrial temperature range of −40°C to +85°C, with operational capabilities up to 125°C. It features a gain programmable architecture, allowing the gain to be set with a single external resistor over a range of 1 to 1000.

This amplifier is available in an 8-lead MSOP package, which is particularly useful for space-constrained and multichannel applications due to its compact size.
