TSC2111IRGZT-4-Wire Touch Screen Controller, St. DAC / Mono ADC, 6 audio in. and HP/Spk Amplifier

The TSC2111 is a low-power highly integrated high performance codec and touch screen controller, which supports stereo audio DAC, mono audio ADC and SAR ADC.

The TSC2111 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 TSC2111 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.

The TSC2111 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 TSC2111 offers battery measurement inputs capable of reading battery voltages up to 6 V, while operating at only 3 V. It also has an on-chip temperature sensor capable of reading 0.3°C resolution. The TSC2111 is available in a 48-lead QFN.
