DESCRIPTION
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. The digital
audio data is transferred through a standard I
2
S
interface.
The TSC2300 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 TSC2300 is available in a 64-lead TQFP.
