ADS7846AE TI Touch Screen Controller | 16-TSSOP | 12-bit, 4-Wire

Product Overview

The ADS7846AE is a complete analog-to-digital converter (ADC) and touch screen controller from Texas Instruments. It features a 12-bit successive approximation register (SAR) ADC with a synchronous serial interface and low on-resistance switches for driving the touch screen. The device operates from a single 2.2V to 5.25V supply and is available in a compact 16-pin TSSOP package. It is designed for battery-powered systems such as personal digital assistants (PDAs), smart phones, and other portable devices requiring a resistive touch screen interface.
