ADS7845 - 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 750µW at a 125kHz throughput rate and a +2.7V supply.
The reference voltage (VREF) can be varied between 1V an
