TOUCH PANEL CONTROLLER

DESCRIPTION

The UTC TS2043 is a highly integrated 12-bit SAR

analog-to-digital (A/D) converter designed for touch panel

controllers. It features serial interface and low on-resistance drivers

for 4-wire resistive touch panels. The UTC TS2043 contains all the

analog and digital circuitry needed to complete a pen request.

The UTC TS2043 features a low-power dissipation consumes

only 800uW under a 125KHz sample rate and in a 2.7V supply

condition, it consumes only 2.7uW at shutdown mode. The supply

voltage is from 2.7V to 5.5V under normal operation.

The UTC TS2043 can be used in applications such as touch

panels, personal digital Assistants (PDAs), smart phones,

point-to-sales terminals, high speed data acquisition, portable

instruments, and low power instruments.
