GENERAL DESCRIPTION
The AD79801 is a 16-bit, successive approximation, analog-to-
digital converter (ADC) that operates from a single power supply,
VDD. It contains a low power, high speed, 16-bit sampling ADC
and a versatile serial interface port. On the CNV rising edge, it
samples an analog input, IN+, between 0 V to REF with respect
to a ground sense, IN−. The reference voltage, REF, is applied
externally and can be set independent of the supply voltage,
VDD. Its power scales linearly with throughput.
The SPI-compatible serial interface also features the ability,
using the SDI input, to daisy-chain several ADCs on a single,
3-wire bus and provides an optional busy indicator. It is compatible
with 1.8 V, 2.5 V, 3 V, or 5 V logic, using the separate supply VIO.
The AD7980 is housed in a 10-lead MSOP or a 10-lead LFCSP
with operation specified from −40°C to +125°C.
