DESCRIPTION

The TSC2302 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, and

8-bit D/A converter (DAC) output for LCD contrast

control. The TSC2302 offers programmable resolution

of 8, 10, and 12 bits and sampling rates up to 125 kHz

to accommodate different screen sizes. The TSC2302

interfaces to the host controller through a standard SPI

serial interface.

•

Stereo Audio Codec

– 20-Bit Delta-Sigma ADC/DAC

– Dynamic Range: 98 dB

– Sampling Rate Up to 48 kHz

– I²S Serial Interface

The TSC2302 features a high-performance 20-bit,

48-ksps stereo audio codec with highly integrated

analog functionality. The audio portion of the TSC2302

contains microphone input with built-in pre-amp and

microphone bias circuit, an auxiliary stereo analog

– Stereo 16-Ω Headphone Driver

Effects Processing

input,

a mono line-level output, and a stereo

headphone amplifier output. The digital audio data is

transferred through a standard I²S interface. A fully

programmable PLL for generating audio clocks from a

wide variety of system clocks is also included.

•

Single 2.7-V to 3.6-V Supply

48-pin QFN Package

The TSC2302 also offers two battery measurement

inputs capable of battery voltages up to 6 V, while

operating at a supply voltage of only 2.7 V. It also has

an on-chip temperature sensor capable of reading

0.3°C resolution. The TSC2302 is available in a

48-lead QFN.
