Description
The AD7879-1ACPZ-500R7 is a touch screen controller with 12-bit successive approximation analog-to-digital converter (ADC), synchronous serial interface, and low on-resistance switches. It is designed to work with a single 1.6 V to 3.6 V low power supply and has a maximum throughput rate of 105 kSPS. The device features a shutdown mode that reduces its current consumption to less than 6 μA, making it an energy-efficient choice. The AD7879-1ACPZ-500R7 has a WLCSP package that measures 12-ball, 1.6 mm x 2 mm or a LFCSP package that measures 16-lead, 4 mm x 4 mm.
