The AD7688 is a 16-bit, 500 kSPS, charge redistribution successive-approximation Analog-to-Digital Converter which operates from a single 5V power supply, VDD. It contains a very low power high-speed 16-bit sampling ADC with no missing codes, an internal conversion clock and a versatile serial interface port. The part also contains a low noise, wide bandwidth, very short aperture delay track/hold circuit. On the CNV rising edge, it samples the voltage difference between IN+ and IN- pins. The voltages on these pins usually swing in opposite phase between 0 V to REF. The reference voltage REF is applied externally and can be set up to the supply voltage.

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

EVAL-AD7688-PMDZ

16-Bit, 500 kSPS PulSAR® ADC PMOD Evaluation Board

16-Bit, 500 kSPS PulSAR® ADC PMOD Evaluation Board

Features and Benefits

  • 16-Bit Analog to Digital Converters
  • 500 kSPS
  • Unipolar, Differential Input
  • Standard SPI PMOD header/pin out
  • Connectable to 3rd Party FPGA and MCU Platforms

Product Detail

The PMOD-compatible evaluation/prototyping board is a small form factor, low-cost analog-to-digital conversion option. When prototyping, this board is used in conjunction with your favorite MCU or FPGA development board which has the SPI PMOD peripheral connector. Direct electrical and physical connection will enable you to quickly develop software for your system.

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.
