Analog Devices Inc. EV-ADUM7703-8FMCZ

Overview

EV-ADuM7703-8FMCZ from Analog Devices is a fully featured evaluation board for the ADuM7703 - a 16-bit, isolated, second-order sigma-delta ADC with on-chip iCoupler® digital isolation and 5 kV rms reinforced isolation rating. It supports standalone operation or SDP-H1 controller board integration, includes on-board ADuM6000 isoPower®, ADP2360 buck regulator, and ADP7104 LDO, and enables full characterization of analog input (±250 mV), MCLK-driven serial interface, and isolated data stream output.

For engineers reviewing the EV-ADuM7703-8FMCZ datasheet, EV-ADuM7703-8FMCZ pinout, EV-ADuM7703-8FMCZ application, or EV-ADuM7703-8FMCZ equivalent, this page delivers verified hardware configuration details, ACE software integration guidance, SDP-H1 interface requirements, external power supply options (J5/J6/J7), and isolated ADC evaluation best practices - all specific to the shipped default setup in SDP-H1 controlled mode.

Technical Context

The EV-ADuM7703-8FMCZ implements a complete signal chain for evaluating the ADuM7703's isolated Σ-Δ conversion: it routes analog inputs via J1/J2 connectors, supplies VDD1 (isolated 5 V) through ADuM6000 or externally via J5/J7, and powers VDD2 (3.3 V or 5 V) from SDP-H1 or ADP7104ARDZ-5.0. Link configurations (LK1–LK8) define supply sourcing, ground isolation, and serial interface routing (MCLK/MDAT).

Hardware-level isolation is enforced by physically separated GND1/GND2 planes with 8.1 mm creepage/clearance. Communication occurs either through the 160-pin SDP-H1 interface (default) or standalone SMB jacks (J3/J4), with FPGA-based decimation and sample rate control managed via ACE software - supporting waveform, histogram, and FFT analysis of the single-bit data stream output.

FAQ

What is the primary function of the EV-ADuM7703-8FMCZ?

The EV-ADuM7703-8FMCZ is an evaluation board purpose-built to characterize the ADuM7703 isolated sigma-delta ADC. It provides full hardware support - including isolated power (ADuM6000), regulated supplies (ADP2360, ADP7104), configurable link settings (LK1–LK8), and SDP-H1/standalone interface options - enabling engineers to validate performance metrics such as SNR, THD, and linearity under real-world isolated conditions. The EV-ADuM7703-8FMCZ itself contains no ADC; it hosts and interfaces with the ADuM7703 IC.

Does the EV-ADuM7703-8FMCZ include the ADuM7703 IC?

Yes, the EV-ADuM7703-8FMCZ evaluation board ships with the ADuM7703 IC pre-mounted and fully integrated into the signal chain. The board is not a bare platform - it is a functional, ready-to-use system that includes the target 16-bit isolated ADC, on-board isolated power generation, analog input conditioning, and digital interface circuitry required to operate and evaluate the ADuM7703 per its datasheet specifications.

What software is required to operate the EV-ADuM7703-8FMCZ?

The EV-ADuM7703-8FMCZ requires Analog Devices' Analysis Control Evaluation (ACE) software with the ADuM7703 plugin. ACE provides full control of the SDP-H1 FPGA, captures time-domain waveforms, computes histograms for DC performance, and performs FFT analysis on the ADuM7703's single-bit output stream. The software is Windows-only (Vista SP2 through Windows 10, 32/64-bit), and SDP-H1 drivers must be installed before connecting the EV-ADuM7703-8FMCZ to ensure proper enumeration.

Can the EV-ADuM7703-8FMCZ operate without the SDP-H1 controller board?

Yes, the EV-ADuM7703-8FMCZ supports standalone operation using the J3 SMB jack for MCLK input and J4 SMB jack for MDAT output. In this mode, users must provide an external clock source and capture/decode the single-bit data stream independently. However, ACE software functionality - including waveform display, histogram, and FFT - is only available when used with the SDP-H1 board, as the FPGA-based processing and USB communication depend on that controller.

What are the critical power supply constraints for safe operation of the EV-ADuM7703-8FMCZ?

Three critical constraints apply: (1) When SDP-H1 is connected, VDD2 supplied via J6 must not exceed 3.3 V - exceeding this damages the SDP-H1 board; (2) Analog input must stay within ±250 mV (±320 mV full-scale) to avoid clipping or damage to the ADuM7703; (3) External HIGH_V (J7) must be strictly 23–25 V - outside this range risks overvoltage on the ADP2360 buck regulator. All link positions (especially LK1, LK2, LK5) must match the selected power configuration before applying power.
