Product Introduction

Overview

The ADG731BSUZ, produced by Analog Devices Inc., is a monolithic, CMOS, 32-channel analog multiplexer. It features a serially controlled 3-wire interface compatible with SPI, QSPI, MICROWIRE, and some DSP interface standards. This device is designed to switch one of 32 inputs (S1–S32) to a common output, D, making it versatile for various applications. The ADG731 operates from a single supply of 1.8 V to 5.5 V or a ±2.5 V dual supply, ensuring broad compatibility and reliability.
