GENERAL DESCRIPTION

The AD7983 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 AD7983 is housed in a 10-lead MSOP or a 10-lead QFN

(LFCSP) with operation specified from −40°C to +85°C.
