5-wire Touch Screen Controller

The ADS7845 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?W 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 0.5?W. The ADS7845 is guaranteed down to 2.7V operation.Low power, high speed, and on-board switches make the ADS7845 ideal for battery-operated systems such as personal digital assistants with resistive Touch Screens and other portable equipment. The ADS7845 is available in a 16-lead SSOP package and is guaranteed over the -40?C to +85?C temperature range.
