FEATURES ● 4-WIRE TOUCH SCREEN INTERFACE ● RATIOMETRIC CONVERSION ● SINGLE SUPPLY: 2.7V to 5V ● UP TO 125kHz CONVERSION RATE ● SERIAL INTERFACE ● PROGRAMMABLE 8- OR 12-BIT RESOLUTION ● 2 AUXILIARY ANALOG INPUTS ● FULL POWER-DOWN CONTROL DESCRIPTION The ADS7843 is a 12-bit sampling Analog-to-Digital Converter (ADC) with a synchronous serial interface and low onresistance 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. Low power, high speed, and onboard 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 available in an SSOP-16 package and is specified over the –40°C to +85°C temperature range. APPLICATIONS ● PERSONAL DIGITAL ASSISTANTS ● PORTABLE INSTRUMENTS ● POINT-OF-SALES TERMINALS ● PAGERS ● TOUCH SCREEN MONITORS
