Product Introduction

Overview

The AD620BRZ, produced by Analog Devices Inc., is a low-cost, high-accuracy instrumentation amplifier. It is designed to require only one external resistor to set gains ranging from 1 to 10,000. This amplifier features 8-lead SOIC packaging, which is smaller than discrete designs and offers lower power consumption, making it suitable for battery-powered, portable, or remote applications. The AD620BRZ is ideal for precision data acquisition systems, medical applications such as ECG and noninvasive blood pressure monitors, and other applications requiring high accuracy and low noise.
