Description

The TSC2301 is a highly integrated PDA analog interface circuit. It contains a complete 12-bit A/D resistive touch screen converter (ADC) including drivers, touch pressure measurement capability, keypad controller, and 8-bit D/A converter (DAC) output for LCD contrast control. The TSC2301 offers programmable resolution of 8, 10, and 12 bits and sampling rates up to 125 kHz to accommodate different screen sizes. The TSC2301 interfaces to the host controller through a standard SPI serial interface.

The TSC2301 features a high-performance 20-bit, 48-ksps stereo audio codec with highly integrated analog functionality. The audio portion of the TSC2301 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.
