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.
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
input, a mono line-level output, and a stereo
headphone amplifier output. The digital audio data is
transferred through a standard I
2
S interface. A fully
programmable PLL for generating audio clocks from a
wide variety of system clocks is also included.
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擄C resolution. The TSC2302 is available in a
48-lead QFN.
