PDA ANALOG INTERFACE CIRCUIT
DESCRIPTIONThe TSC2000 is a complete PDA analog interface circuit. It
contains a complete 12-bit, Analog-to-Digital (A/D) resistive
touch screen converter including drivers, the control to mea-
sure touch pressure, and an 8-bit Digital-to-Analog (D/A)
converter output for LCD contrast control. The TSC2000
interfaces to the host controller through a standard SPI™
serial interface. The TSC2000 offers programmable resolution
and sampling rates from 8- to 12-bits and up to 125kHz to
accommodate different screen sizes.
The TSC2000 also offers two battery-measurement inputs,
one of which is capable of reading battery voltages up to 6V
while operating at only 2.7V. It also has an on-chip temperature
sensor capable of reading 0.3°C resolution. The TSC2000 is
available in a TSSOP-20 package.
