Product Introduction

Overview

The ADG5421BRMZ is a high-performance, monolithic industrial CMOS analog switch produced by Analog Devices Inc. This device features two independent single-pole single-throw (SPST) switches, making it ideal for various analog signal switching applications. The ADG5421 is known for its ultralow on-resistance and on-resistance flatness, which are critical for low distortion in data acquisition and gain switching applications.

The device operates from dual supplies up to ±22 V, allowing it to handle bipolar analog signals. It also features latch-up immune construction and high ESD ratings, enhancing its robustness in harsh environments.
