TSC2300 20 位 48Ksps I2S 音频编解码器（单声道 ADC、立体声 DAC）
TSC2300 说明
The TSC2300 is a highly integrated PDA analog interface circuit. It contains a complete 12-bit A/D resistive touch screen converter including drivers, touch pressure measurement capability, keypad controller and 8-bit D/A converter output for LCD contrast control. The TSC2300 offers programmable resolution of 8, 10, and 12 bits and sampling rates up to 125 kHz to accommodate different screen sizes. The TSC2300 interfaces to the host controller through a standard SPI serial interface.
The TSC2300 features a high-performance 20-bit, 48-ksps audio codec with highly integrated analog functionality. The audio portion of the TSC2300 contains microphone input with built-in pre-amp and microphone bias circuit, an auxiliary stereo analog input, a stereo line-level output, a differential mono line-level output, and a stereo headphone amplifier output.
