GENERAL DESCRIPTION
The AD7980 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 QFN
(LFCSP) with operation specified from 40°C to +125°C.
