The ADS7843-Q1 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 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-Q1 is specified down to 2.7V operation.

Low power, high speed, and onboard switches make the ADS7843-Q1 ideal for battery-operated systems such as personal digital assistants with resistive touch screens and other portable equipment. The ADS7843-Q1 is available in an SSOP-16 package and is specified over the –40°C to +85°C temperature range.
