Analog Devices Inc. EVAL-AD4630-24FMCZ

Overview

EVAL-AD4630-24FMCZ from Analog Devices is a Rev E FPGA Mezzanine Card (FMC)-LPC evaluation board designed to accelerate prototyping and performance validation of the AD4630-24 - a dual-channel, 24-bit, 2 MSPS precision SAR ADC. It integrates an ADR4550 voltage reference, ADA4945-1/ADA4896-2 configurable analog front end, on-board 100 MHz low-jitter clock oscillator, and full power regulation from a 12 V FMC supply - enabling high-fidelity data acquisition in metrology and precision instrumentation labs.

For engineers reviewing the EVAL-AD4630-24FMCZ datasheet, EVAL-AD4630-24FMCZ pinout, EVAL-AD4630-24FMCZ application, or EVAL-AD4630-24FMCZ equivalent, key selection considerations include FMC-LPC compatibility with Xilinx Zynq-7000 SoC controller boards (e.g., Digilent ZedBoard), support for multiple AFE topologies (differential driver, dual buffer, direct drive), ACE software integration, and revision-specific power tree (7.5 V intermediate rail, ±6.5 V/–3.3 V amplifier supplies).

Technical Context

The EVAL-AD4630-24FMCZ implements a modular signal chain architecture centered on the AD4630-24 ADC, interfacing via SPI over FMC-LPC to a Zynq-7000-based host (e.g., ZedBoard). Its hardware supports three distinct analog front-end configurations: default ADA4945-1 differential driver (optimized for distortion), ADA4896-2 dual-buffer topology (optimized for noise, 1 nV/√Hz), and direct SMA-to-ADC path for external driver evaluation.

Power delivery uses a two-stage regulation scheme: 12 V input → +7.5 V switcher → LDOs generating +5.4 V (ADC core), +3.3 V (digital logic), +1.8 V (ADC core & I/O), VAMP+ (+6.5 V) and VAMP− (−3.3 V) for amplifiers, with all rails accessible via test turrets. Clocking defaults to an on-board 100 MHz XO but accepts external <100 MHz sources via SMA (J6), requiring 10–12 dBm level and low jitter for optimal SNR.

FAQ

What is the primary controller board supported by the EVAL-AD4630-24FMCZ?

The EVAL-AD4630-24FMCZ is designed for use with the Digilent ZedBoard, which hosts a Xilinx Zynq-7000 SoC (dual ARM Cortex-A9 + FPGA fabric). The ZedBoard connects to the EVAL-AD4630-24FMCZ via the FMC-LPC interface and provides SPI communication, power regulation, and Linux-based data capture - all required for full operation of the EVAL-AD4630-24FMCZ. ACE software communicates with the ZedBoard over USB OTG to configure and acquire data from the EVAL-AD4630-24FMCZ.

Does the EVAL-AD4630-24FMCZ support both single-ended and differential input signals?

Yes, the EVAL-AD4630-24FMCZ supports both signal types across all AFE configurations. In the default ADA4945-1 differential driver mode, it accepts either differential inputs (IN_A+/IN_A−, IN_B+/IN_B−) or single-ended sources (with unused input terminated to source impedance). The ADA4896-2 dual-buffer configuration similarly accommodates both, and the direct-drive mode allows external signal conditioning before injection into the AD4630-24. All configurations preserve polarity awareness per channel, with documented inversion handling guidance in the User Guide for DC-coupled measurements.

What are the key differences between Rev C and Rev E of the EVAL-AD4630-24FMCZ?

Rev E replaces the obsolete Rev C with significant hardware upgrades: a new ADR4550 5 V reference (vs. LTC6655 in Rev C), improved power tree using +7.5 V intermediate rail (vs. +5.7 V), enhanced amplifier supplies (VAMP+ up to +6.5 V, VAMP− at −3.3 V), additional external power input options (J7/J8), and updated AFE flexibility including VOCM generation circuitry. Rev E boards have date code DC>2435 and feature revised layout, decoupling, and thermal design - all documented in the AD4630/AD4030 Evaluation Board User Guide.

Can the EVAL-AD4630-24FMCZ be used without the ZedBoard?

No - the EVAL-AD4630-24FMCZ lacks onboard processing, memory, or USB/Ethernet interfaces and relies entirely on a compatible FMC-LPC host such as the ZedBoard for SPI control, data buffering (DDR3), ACE software interaction, and boot firmware execution. While the board provides turrets for manual power injection and external clock/reference inputs, the ZedBoard (or functionally equivalent FMC-capable controller) is mandatory for functional evaluation of the AD4630-24 using the EVAL-AD4630-24FMCZ.

Which software tools are required to operate the EVAL-AD4630-24FMCZ?

Operation requires Analog Devices' ACE (Analysis, Control, Evaluation) software, installed on a Windows PC (7/10), along with the dedicated EVAL-AD4630-24FMCZ plug-in. ACE manages ZedBoard boot (via included SD card with ADI Kuiper Linux), configures the AD4630-24 registers, captures streaming samples, and performs real-time FFT, histogram, and DC accuracy analysis. No separate FPGA bitstream loading or low-level driver development is needed - ACE delivers a fully integrated GUI experience for the EVAL-AD4630-24FMCZ.
