ADS7843IDBQRQ1 TI Touch Screen Controller | 16-SSOP | 12-bit, 4-Wire

Product Overview

The ADS7843IDBQRQ1 is a high-performance, 4-wire resistive touch screen controller from Texas Instruments, designed for automotive and industrial applications. It features a 12-bit successive approximation register (SAR) ADC with a synchronous serial interface, providing accurate touch position measurement. The device operates from a single 2.2V to 5.25V supply and includes an on-chip 2.5V reference, reducing external component count. Housed in a compact 16-SSOP package, it is qualified to AEC-Q100 for automotive reliability.
