Analog Devices Inc. EVAL-AD4858FMCZ

Overview

EVAL-AD4858FMCZ from Analog Devices is a ZedBoard-compatible FMC evaluation board designed to demonstrate the AD4858 8-channel, simultaneous sampling, 20-bit, 1 MSPS data acquisition system (DAS). It provides full access to configuration options via ACE software, includes on-board LTC6655 reference and LT1761/LT8330 power regulation, and supports differential analog inputs through eight SMA connectors.

For engineers reviewing the EVAL-AD4858FMCZ datasheet, EVAL-AD4858FMCZ pinout, EVAL-AD4858FMCZ application, or EVAL-AD4858FMCZ equivalent, this page delivers verified hardware link options, jumper-configurable power rails (+24 V/−24 V/5 V/2.5 V/1.8 V), FMC interface compatibility, Linux-based embedded firmware, and ACE GUI-driven time/frequency domain analysis - all critical for high-precision DAS validation workflows.

Technical Context

The EVAL-AD4858FMCZ implements a complete signal chain for evaluating the AD4858 DAS, including configurable bipolar high-voltage supplies (VCC/VEE), low-noise LDOs (LT1761) for VDD/VDDH/VIO, and a boost converter (LT8330) for ±24 V generation. It supports both internal and external reference modes using the AD4858's REFIO/REFBUF pins with optional R62/R46 routing.

Hardware flexibility is enabled via factory-default jumpers (JV12V, JSHIFT, JVCC, JVEE, JVDDH, JVDD, JVDDL, JVIO, JVIO_LDO) that define supply sourcing, voltage levels, and digital I/O logic thresholds. The board interfaces exclusively through the FMC-LPC connector (P1) and operates under Industrial I/O (IIO) architecture for host PC control via pyadi-iio or MATLAB Precision Toolbox.

FAQ

What is the primary purpose of the EVAL-AD4858FMCZ?

The EVAL-AD4858FMCZ is an FMC-form-factor evaluation board built to fully characterize the AD4858 8-channel, 20-bit, 1 MSPS simultaneous sampling DAS. It enables rapid prototyping and performance validation using ACE software, on-board regulated supplies, and differential SMA inputs - all without requiring custom carrier board development. The EVAL-AD4858FMCZ integrates reference, power, and interface subsystems to isolate AD4858 behavior in real-world signal chain conditions.

Which controller boards are compatible with the EVAL-AD4858FMCZ?

The EVAL-AD4858FMCZ is explicitly validated for use with the Digilent ZedBoard and is compatible with other FMC-LPC controller boards supporting the same mechanical and electrical interface specifications. Its design follows ANSI/VITA 57.1-2010 standards, and the embedded firmware targets Xilinx Zynq-7000 SoC platforms running ADI Kuiper Linux. ACE software detects the EVAL-AD4858FMCZ only when paired with supported controllers and the correct FPGA image.

Does the EVAL-AD4858FMCZ support external voltage references?

Yes, the EVAL-AD4858FMCZ includes an LTC6655 4.096 V reference and supports two external reference configurations per the AD4858 datasheet: (1) external reference with internal buffer enabled (via REFIO and R62), and (2) external reference with internal buffer disabled (via REFBUF, R46, and REFIO grounded). These options allow users to evaluate noise, drift, and settling performance trade-offs between internal and high-precision external references on the EVAL-AD4858FMCZ.

How is power supplied to the EVAL-AD4858FMCZ?

By default, the EVAL-AD4858FMCZ receives unregulated 12 V from the ZedBoard via the FMC connector (JV12V in Position A), then generates all required rails internally: ±24 V via LT8330, and +5 V/+2.5 V/+1.8 V via LT1761 LDOs. External 12 V can be applied via V12V_EXT (JV12V Position B), and individual supply pins (VCC, VEE, VDD, etc.) may be overridden using dedicated jumpers (JVCC, JVEE, etc.) for custom power architecture testing.

Can the EVAL-AD4858FMCZ be used to evaluate other ADI DAS devices?

Yes - the EVAL-AD4858FMCZ user guide explicitly states it can also evaluate the AD4856, AD4854, and AD4852. This cross-compatibility arises from shared pinout, register map, and signal chain architecture across the AD485x family. However, users must confirm voltage, timing, and configuration register differences in each respective datasheet, as jumper defaults and ACE plugin settings may require adjustment for non-AD4858 variants.
