The AD7873ACP is a 12-bit successive approximation ADC with a synchronous serial interface, designed for 4-wire resistive touch screens. It operates from a single 2.2V to 5.25V supply and achieves a throughput rate of 125 kSPS. The device includes an on-chip 2.5V reference, temperature sensor, and battery measurement capabilities.
Key specifications include programmable 8-bit or 12-bit resolution, ratiometric conversion, and a high-speed serial interface (SPI). Power dissipation is 1.37 mW maximum with reference off, and 2.41 mW typical with reference on. The device features a shutdown mode with 1 µA maximum current. It also provides one auxiliary analog input and supports touch pressure measurement.
The AD7873ACP is available in a 16-LFCSP-VQ (4x4) package, surface mount. Typical applications include personal digital assistants, hand-held devices, touch screen monitors, point-of-sale terminals, and pagers.
