TSC2100 具有立体声音频编解码器和耳机/扬声器放大器的可编程 4 线触摸屏控制器

TSC2100 说明

The TSC2100 is a highly integrated touch screen controller with on-chip processor and audio codec. The touch screen portion of the TSC2100 contains a 12-bit 4-wire resistive touch screen ADC complete with drivers, and interfaces to the host controller through a standard SPITM 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 TSC2100 includes a high-performance audio codec with 16/20/24/32-bit 97-dB stereo playback, mono record functionality at up to 48 ksps.Ohm
