500 kSPS 16- BIT Differential PulSAR® A/D Converter in µSOIC/QFN
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 AD7688 is housed in a 10-lead µSOIC or 10-lead QFN (Chip Scale package) with operation
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, low power, 5.0 kVrms isolation , we recommend the ADUM4401 .
- For SPI Interface, smallest package, low voltage I/O (1.8 V to 5.5 V) , we recommend the ADUM3481 .
- 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 high frequency, low noise, low distortion applications , we recommend the ADA4897-1 or the AD8021 .
- For low frequency, precision, low bias current applications , we recommend the ADA4627-1, ADA4637-1 or the AD8615 .
- For precision, low power, low distortion applications , we recommend the ADA4841-1, ADA4896-2, AD8031 or the AD8031 .
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
