Product Introduction

Overview

The AD620SQ/883B, produced by Analog Devices Inc., is a low-cost, high-accuracy instrumentation amplifier. It is designed to offer superior performance with minimal external components, requiring only one external resistor to set gains from 1 to 10,000. This amplifier is available in 8-lead CERDIP packaging and is known for its low power consumption, with a maximum supply current of 1.3 mA. The AD620SQ/883B is well-suited for battery-powered and portable applications due to its compact size and low power requirements.
