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
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
interface.

The TSC2301 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 TSC2301 is available in 64-lead
TQFP, and 120-ball VFBGA packages.
