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 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 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 available in a 16-lead SSOP package and is guaranteed over the –40°C to +85°C temperature range
