TSC2102 具有立体声音频 DAC 和耳机放大器 PLL 的可编程 4 线触摸屏控制器
TSC2102 说明
The TSC2102 is a highly integrated combination resistive touch screen controller with on-chip processor and audio DAC. The touch screen portion of the TSC2102 contains a 12-bit 4-wire resistive touch screen converter complete with drivers, and interfaces to the host controller through a standard SPI™ serial interface. The on-chip processor provides extensive features specifically designed to reduce host processor and bus overhead, with capabilities that include fully automated operating modes, programmable conversion resolution up to 12 bits, programmable sampling rates up to 125 kHz, programmable conversion averaging, and programmable on-chip timing generation.
The TSC2102 also features a high-performance audio DAC with 16, 20, 24, or 32-bit stereo playback functionality at up to 48 ksps.
