Analog Devices Inc. EVAL-AD7626FMCZ

Overview

EVAL-AD7626FMCZ from Analog Devices is a fully featured FMC-form-factor evaluation board designed to demonstrate the AD7626 16-bit, 10 MSPS PulSAR® differential analog-to-digital converter (ADC) in real-world signal acquisition systems. It integrates on-board reference buffers (ADR4540/ADR3412), ADC drivers (ADA4899-1/ADA4932-1), precision regulators (ADP7102/ADP2300), and interfaces via a 160-pin VITA 57 FMC connector to the EVAL-SDP-CH1Z system demonstration platform for USB-controlled data capture and analysis.

For engineers reviewing the EVAL-AD7626FMCZ datasheet, EVAL-AD7626FMCZ pinout, EVAL-AD7626FMCZ application, or EVAL-AD7626FMCZ equivalent, this page provides verified hardware configuration details, supported software workflows, interface compatibility with SDP platforms, and validated analog signal conditioning paths for high-fidelity ADC evaluation.

Technical Context

The EVAL-AD7626FMCZ implements a complete signal chain for the AD7626: dual SMA analog inputs feed configurable amplifier stages (unity-gain buffer or fully differential mode using ADA4899-1 or ADA4932-1), with ±2.5 V and +7 V supplies generated by ADP2300 and ADP7102 regulators. Reference options include internal 4.096 V, external ADR4540 buffered 4.096 V, or ADR3412-derived 1.2 V applied to REFIN.

Communication uses LVDS serial interface (D±, CLK±, DCO±) routed through the 160-pin FMC-LPC connector to the EVAL-SDP-CH1Z's Spartan-6 FPGA and Blackfin processor. The board supports echo-clocked mode only and requires the AD7626_25 Evaluation Software for waveform capture, FFT analysis (SNR, SINAD, THD, SFDR), histogram testing, and DC/AC performance validation.

FAQ

What is the primary purpose of the EVAL-AD7626FMCZ?

The EVAL-AD7626FMCZ is an evaluation board specifically built to characterize the AD7626 16-bit, 10 MSPS differential SAR ADC. It provides a complete, calibrated signal chain-including analog input conditioning, precision references, power regulation, and LVDS interface-to enable accurate time-domain and frequency-domain performance validation in lab and design environments. The EVAL-AD7626FMCZ requires the EVAL-SDP-CH1Z platform and AD7626_25 Evaluation Software for full operation.

Which host platform does the EVAL-AD7626FMCZ require to operate?

The EVAL-AD7626FMCZ must be used with the EVAL-SDP-CH1Z System Demonstration Platform board. It connects exclusively via the 160-pin VITA 57 FMC-LPC connector (J7) and relies on the SDP's Spartan-6 FPGA and Blackfin processor for USB communication, clock generation, and data acquisition control. No standalone operation or alternative host interfaces are supported per the UG-745 user guide.

Does the EVAL-AD7626FMCZ support both AD7625 and AD7626 devices?

Yes - the EVAL-AD7626FMCZ shares hardware and firmware compatibility with the AD7625 (6 MSPS) as part of the jointly documented EVAL-AD7625FMCZ/EVAL-AD7626FMCZ platform. The board supports both ICs via software-selectable throughput settings: default 10,000 kSPS for EVAL-AD7626FMCZ and 6,000 kSPS for AD7625. Physical layout, reference circuitry, and amplifier configurations are identical across both variants.

What reference voltage options are available on the EVAL-AD7626FMCZ?

The EVAL-AD7626FMCZ supports three reference configurations: (1) internal 4.096 V reference (default), (2) external ADR4540 4.096 V reference buffered by AD8031 (LK3 inserted), or (3) ADR3412 1.2 V reference applied to REFIN to generate internal 4.096 V (LK2 inserted). Selection is controlled via jumper links LK2/LK3 and software EN0/EN1 bits per the AD7626 datasheet.

Can the EVAL-AD7626FMCZ be powered independently of the EVAL-SDP-CH1Z?

No - primary power (12 V) is supplied exclusively through the 160-pin FMC connector (J7) from the EVAL-SDP-CH1Z. While the board includes a 3-pin terminal (J4) for optional external ±VS supplies to the analog amplifiers, all digital logic, FPGA interface, EEPROM, and core regulation depend on the SDP board. The EVAL-AD7626FMCZ has no onboard AC/DC converter or independent power entry.
