The TSC2004IRTJT is a very low-power Touch Screen Controller designed to work with power-sensitive, handheld applications that are based on advanced low-voltage processors. It works with a supply voltage as low as 1.2V, which can be supplied by a single-cell battery. It contains a complete ultralow-power 12-bit analog-to-digital (A/D) resistive touch screen converter, including drivers and the control logic to measure touch pressure.
