AD7889, AD7879, Low Voltage Controller
The AD7879/AD7889 are 12-bit successive approximation analog-to-digital converters (SAR ADCs) with a synchronous serial interface and low on-resistance switches for driving 4-wire resistive touch screens.
The AD7879/AD7889 work with a very low power supply *a single 1.6 V to 3.6 V supply <
