DESCRIPTION

The ADS7843 is a 12-bit sampling analog-to-digital

converter (ADC) with a synchronous serial interface

and low on-resistance switches for driving touch

screens. Typical power dissipation is 750

μW at a

125kHz throughput rate and a +2.7V supply. The

reference voltage (V

REF) can be varied between 1V and

+V

CC, providing a corresponding input voltage range

of 0V to V

REF. The device includes a shutdown mode

which reduces typical power dissipation to under

0.5

μW. The ADS7843 is guaranteed down to 2.7V

operation.

Low power, high speed, and on-board switches make

the ADS7843 ideal for battery operated systems such

as personal digital assistants with resistive touch screens

and other portable equipment. The ADS7843 is avail-

able in a 16-lead SSOP package and is guaranteed

over the –40

°C to +85°C temperature range.

APPLICATIONS

q PERSONAL DIGITAL ASSISTANTS

q PORTABLE INSTRUMENTS
