ADS7843  
SBAS090B SEPTEMBER 2000 REVISED MAY 2002  
TOUCH SCREEN CONTROLLER  
DESCRIPTION  
FEATURES  
4-WIRE TOUCH SCREEN INTERFACE  
RATIOMETRIC CONVERSION  
SINGLE SUPPLY: 2.7V to 5V  
UP TO 125kHz CONVERSION RATE  
SERIAL INTERFACE  
The ADS7843 is a 12-bit sampling Analog-to-Digital Con-  
verter (ADC) with a synchronous serial interface and low on-  
resistance switches for driving touch screens. Typical power  
dissipation is 750µW at a 125kHz throughput rate and a  
+2.7V supply. The reference voltage (VREF) can be varied  
between 1V and +VCC, providing a corresponding input  
voltage range of 0V to VREF. The device includes a shutdown  
mode which reduces typical power dissipation to under  
0.5µW. The ADS7843 is specified down to 2.7V operation.  
PROGRAMMABLE 8- OR 12-BIT RESOLUTION  
2 AUXILIARY ANALOG INPUTS  
FULL POWER-DOWN CONTROL  
Low power, high speed, and onboard switches make the  
ADS7843 ideal for battery-operated systems such as per-  
sonal digital assistants with resistive touch screens and other  
portable equipment. The ADS7843 is available in an  
SSOP-16 package and is specified over the –40°C to +85°C  
temperature range.
