Product Introduction

Overview

The AD7734BRUZ is a high-precision, high-throughput analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of the AD7734 family and is designed for high-resolution multiplexing applications. It features a 24-bit sigma-delta architecture, providing true 16-bit peak-to-peak resolution with a total conversion time of 500 μs, making it suitable for applications requiring high data throughput and precision.

The AD7734BRUZ operates from a single +5 V analog supply and includes four single-ended input channels with unipolar or true bipolar input ranges up to ±10 V. It also supports overrange and underrange detection and can handle analog input overvoltages up to ±16.5 V without affecting adjacent channels.
