Product Introduction

Overview

The AD621BNZ, produced by Analog Devices Inc., is a low-cost, low-power, high-accuracy instrumentation amplifier. It is designed for a wide range of applications, offering high performance, small size, and low power consumption, making it superior to discrete in-amp implementations. The AD621BNZ is easy to use, with pin-strappable gains of 10 and 100, and all errors specified for total system performance. This amplifier is particularly suited for applications where power dissipation, size, and weight are critical, such as in portable or remote devices.
