Power dissipation 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 or provides an optional busy indicator. This device is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic, using the separate supply VIO.
The AD7686 is housed in a 10-lead MSOP or a 10-lead QFN (LFCSP) with operation specified from −40°C to +85°C.

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
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, smallest package, low voltage I/O (1.8 V to 5.5 V) , we recommend the ADUM3481 .
- For SPI Interface, low power, 5.0 kVrms isolation , we recommend the ADUM4401 .
- For SPI Interface, enhanced system-level ESD performance, 2.5 kVrms isolation , we recommend the ADUM3401 .
- For SPI Interface, lowest power, 2.5 kVrms isolation , we recommend the ADUM1401 .
Recommended Driver Amplifiers
- For low frequency, precision, low bias current applications , we recommend the ADA4627-1, ADA4637-1 or the AD8615 .
- For high frequency, low noise, low distortion applications , we recommend the ADA4807-1, ADA4807-2, ADA4897-1 or the ADA4897-2 .
- For precision, low power, low distortion applications , we recommend the ADA4805-1, ADA4805-2, ADA4841-1 or the ADA4841-2 .
