TSC2200IRHB

具有 12 位 125kHz ADC 和键盘接口的可编程 4 线触摸屏控制器 32-VQFN -40 to 85

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 0.3°C resolution. The TSC2200 is available in a TSSOP-28 and a QFN-32 package.
