ADS7846IRGVT TI Touch Screen Controller | 16-VQFN (4x4) | 12-bit, 4-Wire, SPI

Product Overview

The ADS7846IRGVT is a high-performance, 12-bit analog-to-digital converter (ADC) with a synchronous serial interface, designed specifically for 4-wire resistive touch screen applications. Manufactured by Texas Instruments, this device features a low-power, single-supply operation from 2.2V to 5.25V, making it ideal for battery-powered systems. The ADS7846IRGVT is housed in a compact 16-pin VQFN package (4x4 mm), enabling space-constrained designs. It includes a touch screen driver, a 12-bit ADC, and a digital interface, providing a complete touch screen solution.
