Product Introduction

Overview

The AD620ARZ is a low-cost, high-accuracy instrumentation amplifier produced by Analog Devices Inc. It is designed to offer high performance with minimal external components, making it ideal for a variety of precision applications. The AD620 requires only one external resistor to set gains ranging from 1 to 10,000, and it features low power consumption with a maximum supply current of 1.3 mA. This makes it suitable for battery-powered and portable equipment. The amplifier is available in 8-lead SOIC and DIP packaging, which is smaller and more efficient than discrete designs.
