GENERAL DESCRIPTION

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 supplyâ€”a single 1.6 V to 3.6 V supplyâ€”and feature a throughput rate of 105 kSPS. The devices include a shutdown mode that reduces current consumption to less than 6 Î¼A.
