Product Introduction

Overview

The AD7873ARUZ is a 12-bit touch screen digitizer and successive approximation analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is designed to interface with 4-wire resistive touch screens and offers a range of features that make it suitable for various applications. It operates from a single supply voltage of 2.2V to 5.25V and has a throughput rate of 125 kSPS. The device includes on-chip temperature and battery measurement capabilities, as well as an on-board 2.5V reference voltage. Its compact 16-lead TSSOP package makes it ideal for space-constrained designs.
