ADS7846E/2K5 TI Touch Screen Controller | 16-SSOP | 12-bit, 4-Wire

Product Overview

The ADS7846E/2K5 is a high-performance, low-power, 12-bit analog-to-digital converter (ADC) with a synchronous serial interface, designed specifically for touch screen applications. Manufactured by Texas Instruments (TI), this device features a 4-wire resistive touch screen interface, supporting both X and Y coordinate measurements as well as pressure (Z-axis) measurement. It operates from a single 2.2V to 5.25V supply and includes an on-chip 2.5V reference, making it ideal for battery-powered systems. The ADS7846E/2K5 is available in a compact 16-pin SSOP package, ensuring minimal board space usage.
