Analog Devices Inc. EVAL-AD7403-8FMCZ

Overview

EVAL-AD7403-8FMCZ from Analog Devices is a fully featured evaluation board for the AD7403 16-bit isolated sigma-delta analog-to-digital converter, supporting ±250 mV differential input range, 20 MHz data rate output, and galvanic isolation up to 5 kV. It integrates on-board ADuM6000 isolated DC/DC, ADP2441 step-down regulator, and ADP7104 LDO to power both analog (VDD1) and digital (VDD2) domains independently. Designed for shunt-based current sensing in high-voltage motor drives and industrial inverters.

For engineers reviewing the EVAL-AD7403-8FMCZ datasheet, EVAL-AD7403-8FMCZ pinout, EVAL-AD7403-8FMCZ application, or EVAL-AD7403-8FMCZ equivalent, this page delivers verified hardware configuration details, SDP-H1 controller compatibility, standalone SMB interface options, software-supported FFT/SNR/THD analysis, and precise external supply routing via J5/J6/J7 connectors - all critical for rapid ADC characterization and system-level validation.

Technical Context

The EVAL-AD7403-8FMCZ implements a dual-isolation architecture: analog domain powered by ADuM6000 (5 kV isolation, 5 V output) or ADP2441 (24 V input → 5 V), while digital domain receives 3.3 V from EVAL-SDP-CH1Z or external source via J6. Ground planes GND1 and GND2 are physically isolated with 8 mm creepage/clearance.

It supports two operational modes: SDP-H1-controlled mode (default, using FMCZ connector J9) and standalone mode (using J3 for MCLK and J4 for MDAT). Link configuration (LK1–LK4, LK7–LK8) determines supply sourcing, input grounding, and clock/data routing - no firmware or solder modification required.

FAQ

What is the primary function of the EVAL-AD7403-8FMCZ evaluation board?

The EVAL-AD7403-8FMCZ evaluation board is a dedicated hardware platform for characterizing the AD7403 isolated sigma-delta modulator. It provides complete signal conditioning, isolated power generation (5 kV), configurable supply routing, and PC-based analysis tools - enabling engineers to validate SNR, THD, code distribution, and timing behavior of the EVAL-AD7403-8FMCZ without custom design effort.

Which controller board is required to operate the EVAL-AD7403-8FMCZ in standard mode?

The EVAL-AD7403-8FMCZ requires the EVAL-SDP-CH1Z System Demonstration Platform (SDP-H1) controller board for standard operation. It connects via the FMCZ connector (J9), uses the SDP-H1's 12 V and 3.3 V rails, and communicates over USB through preinstalled drivers - allowing full control of FPGA settings, data capture, and real-time analysis via the official Analog Devices evaluation software for EVAL-AD7403-8FMCZ.

Can the EVAL-AD7403-8FMCZ operate without the EVAL-SDP-CH1Z board?

Yes, the EVAL-AD7403-8FMCZ supports standalone operation using SMB connectors J3 (MCLK input) and J4 (MDAT output), with link settings LK3-C and LK4-B. External supplies must be applied via J5 (VDD1), J6 (VDD2), and proper grounding - enabling use in environments where USB host control is unavailable or where custom clocking is required for timing validation of the EVAL-AD7403-8FMCZ.

What isolation voltage does the EVAL-AD7403-8FMCZ support, and how is it implemented?

The EVAL-AD7403-8FMCZ achieves 5 kV rms galvanic isolation between analog and digital domains using the ADuM6000 iCoupler DC/DC converter. This monolithic transformer-based isolation separates GND1 and GND2 ground planes with 8 mm creepage and clearance, satisfying reinforced insulation standards for industrial drive applications - directly reflecting the isolation capability of the underlying AD7403 device evaluated on the EVAL-AD7403-8FMCZ.

What software tools are included with the EVAL-AD7403-8FMCZ kit?

The EVAL-AD7403-8FMCZ kit includes Windows-compatible evaluation software that supports waveform capture, histogram analysis (DC offset, transition noise), FFT computation (SNR, THD, SINAD), and consolidated reporting. It runs on Windows XP SP3, Vista, or Windows 7 with USB 2.0, loads .csv data files, exports screenshots as JPEG, and interfaces exclusively with the EVAL-AD7403-8FMCZ hardware via the EVAL-SDP-CH1Z - no third-party tools or license keys required.
