TSC2200 说明

The TSC2200 is a complete PDA analog interface circuit. It contains a complete 12-bit, Analog-to-Digital (A/D) resistive touch screen converter including drivers, the control to measure touch pressure, keyboard controller, and an 8-bit Digital-to-Analog (D/A) converter output for LCD contrast control. The TSC2200 interfaces to the host controller through a standard SPI™ serial interface. The TSC2200 offers programmable resolution and sampling rates from 8- to 12-bits and up to 125kHz to accommodate different screen sizes.

The TSC2200 also offers two battery-measurement inputs capable of reading battery voltages up to 6V, while operating at only 2.7V. It also has an on-chip temperature sensor capable of reading 0.
