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 QFN1 (LFCSP) with operation specified from −40°C to +85°C.

The EVAL-AD7983SDZ is a fully featured evaluation kit for the AD7983. This board operates in stand alone mode or in conjunction with the System Development Platform, EVAL-SDP-CB1Z . When operated with the System Development Platform software is provided enabling the user to perform detailed analysis of the ADC's performance. This software includes the technical note describing the operation and set up of the evaluation board in standalone operation or when operated with the System Development Platform . When operated in standalone mode the ADZS-BRKOUT-EX3 break out board is recommended for access to various control pins.
This board can also be operated as an evaluation board using the System Demonstration Platform (EVAL-SDP-CB1Z) and an adaptor board (SDP-PMD-IB1Z). When operated with the System Demonstration Platform, a LabView software GUI is provided enabling the user to perform analysis of the ADC's performance.
Recommended Digital Isolators
- For SPI Interface, lowest power, 2.5 kVrms isolation , we recommend the ADUM1401 .
