Analog Devices Inc. EVAL-AD7403FMCZ

Overview

EVAL-AD7403FMCZ from Analog Devices is a fully featured FMC-compatible evaluation board designed to characterize the AD7403 16-bit isolated sigma-delta modulator, supporting ±250 mV differential analog input, up to 20 MHz data rate, and galvanic isolation via iCoupler technology - used for high-voltage shunt current monitoring in industrial motor drives and energy metering systems.

For engineers reviewing the EVAL-AD7403FMCZ datasheet, EVAL-AD7403FMCZ pinout, EVAL-AD7403FMCZ application, or EVAL-AD7403FMCZ equivalent, this page delivers verified hardware configuration details, SDP-H1 controller compatibility, on-board isolated power architecture (ADuM6000 + ADP2441), software-supported FFT/SNR/THD analysis, and standalone mode operation via J3/J4 SMB connectors.

Technical Context

The EVAL-AD7403FMCZ implements a complete signal chain for the AD7403 isolated Σ-Δ modulator, including dual-isolated power domains (GND1/GND2 with 8 mm creepage), configurable VDD1 sourcing (ADuM6000, J5, or J7), and VDD2 routing (EVAL-SDP-CH1Z, on-board LDO, or J6). It supports both SDP-H1-controlled and standalone modes via link-selectable MCLK and MDAT paths.

Hardware-level interface flexibility is enabled through FMCZ connector J9 for SDP-H1 integration and discrete SMB jacks (J3 for MCLK input, J4 for MDAT output) for external FPGA or microcontroller control - all while maintaining galvanic isolation integrity between analog and digital sections.

FAQ

What is the primary function of the EVAL-AD7403FMCZ evaluation board?

The EVAL-AD7403FMCZ evaluation board is a dedicated hardware platform for evaluating the AD7403 isolated sigma-delta modulator. It provides full signal chain support - including isolated analog input conditioning, dual-rail isolated power supplies (VDD1/VDD2), FMC-based SDP-H1 connectivity, and PC-based software for real-time waveform, histogram, and FFT analysis - enabling rapid validation of high-accuracy, high-isolation current sensing in applications like motor drives and smart meters.

Which controller board is required to operate the EVAL-AD7403FMCZ in standard mode?

The EVAL-AD7403FMCZ requires the EVAL-SDP-CH1Z system demonstration platform board for standard operation. The two boards connect via the FMCZ connector (J9), allowing USB-powered communication, synchronized clocking (MCLK), and data streaming (MDAT) to a Windows PC running the official Analog Devices evaluation software - eliminating the need for custom interface firmware or hardware.

Can the EVAL-AD7403FMCZ be used without the EVAL-SDP-CH1Z board?

Yes, the EVAL-AD7403FMCZ supports standalone operation. By configuring LK3 to Position C (MCLK from J3 SMB jack) and LK4 to Position B (MDAT output to J4 SMB jack), users can drive the AD7403 modulator directly from an external FPGA or microcontroller - preserving galvanic isolation while enabling integration into custom carrier boards or non-SDP-based test systems.

What power supply options does the EVAL-AD7403FMCZ support for the AD7403's VDD1 rail?

The EVAL-AD7403FMCZ supports three VDD1 supply configurations: (1) isolated 5 V from the on-board ADuM6000 (default, LK1-A), (2) external 5 V ±10% via J5 connector (LK1-B), or (3) external 24 V ±5% via J7 connector stepped down by the ADP2441 regulator (LK5 inserted). All options maintain isolation integrity and are selected via solder jumpers per Table 2 in UG-683.

Does the EVAL-AD7403FMCZ include software, and what analysis capabilities does it provide?

Yes, the EVAL-AD7403FMCZ kit includes evaluation software (on CD and online) for Windows XP/Vista/7. It provides real-time waveform capture, statistical histogram analysis (DC offset, transition noise), FFT-based AC performance metrics (SNR, THD, SINAD), and summary reporting - all with .csv export capability. The software interfaces natively with the EVAL-SDP-CH1Z and requires no third-party tools or license fees to operate the EVAL-AD7403FMCZ.
