Overview

The EVAL-AD488X-FMC is an FMC evaluation board designed to demonstrate the performance of the AD4880 and AD4884 dual-channel, low noise, high speed successive approximation register (SAR) analog-to-digital converters (ADC) with integrated fully differential drivers (FDA) and gain setting resistors.

The evaluation board is designed for use with the Digilent ZedBoard via the FMC connector. The ZedBoard uses a Xilinx Zynq7000 system on chip (SoC) that runs Analog Devices Kuiper Linux and LIBIIO included on the SD card supplied in the evaluation board kit, enabling ADC configuration and data capture.

Full specifications on the AD4880 and AD4884 are available in the respective data sheets and must be consulted with this user guide when using the EVAL-AD488X-FMC evaluation board.

Features:

  • Integrated fully differential ADC drivers

  • Low-voltage digital signaling (LVDS) data output interface.

  • Analog-to-digital converter (ADC) configuration via serial peripheral interface (SPI).

  • Internal or external generation of 1.1V regulated supply rails.

  • Sampling rate capability between 1.25MSPS and 20MSPS.

  • FMC form factor for easy connection to FPGA carrier boards

Applications:

  • Digital imaging

  • Cell analysis

  • Spectroscopy

  • High speed data acquisition

  • Digital control loops, hardware in the loop

  • Power quality analysis

  • Source measurement units

  • Nondestructive test

Warning

All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection. Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.
