TSC2301 Overview
The TSC2301 is a highly integrated PDA analog interface circuit. It contains a plete 12-bit A/D resistive touch screen converter (ADC) including drivers, touch pressure measurement capability, keypad controller, and 8-bit D/A converter (DAC) output for LCD contrast control. The TSC2301 offers programmable resolution of 8, 10, and 12 bits and sampling rates up to 125 kHz to acmodate different screen sizes.
