TSC2101 可编程 4 线触摸屏控制器，具有 6 路音频输入、立体声音频编解码器和耳机/扬声器放大器

TSC2101 说明

The TSC2101 is a low-power highly integrated high performance codec and touch screen controller, which supports stereo audio DAC, monaural voice ADC and SAR ADC.

The TSC2101 features a high-performance audio codec with 16, 20, 24, or 32-bit stereo playback, mono record functionality at up to 48 ksps. The device integrates several analog features such as support for headset interface, cellular headset interface, microphone interface, and speaker and receiver drivers. The device supports auto detection of headset and button press without any glue logic. The TCS2101 has fully programmable audio. The digital audio data format is programmable to work with popular audio standard protocols (I2S, DSP, left/right justified) in master or slave mode, and also includes an on-chip PLL for flexible clock generation capability.
