Analog Devices Inc. EV-ADUM7701-8FMCZ

Overview

EV-ADUM7701-8FMCZ from Analog Devices is a fully featured evaluation board designed to characterize the ADuM7701 - a 16-bit, isolated sigma-delta analog-to-digital converter with on-chip iCoupler digital isolation and 5 kV reinforced isolation rating. It supports pseudo-differential ±250 mV analog input, 21 MHz serial data rate, 86 dB SNR at 78.1 kSPS, and operates with VDD1 = 4.5–5.5 V and VDD2 = 3.0–5.5 V. The board enables lab-based performance validation in high-voltage motor control and energy metering systems.

For engineers reviewing the EV-ADUM7701-8FMCZ datasheet, EV-ADUM7701-8FMCZ pinout, EV-ADUM7701-8FMCZ application, or EV-ADUM7701-8FMCZ equivalent, this page delivers verified hardware configuration details, SDP-H1 controller integration guidance, ACE software workflow notes, isolated power architecture (ADuM6000 + ADP2360 + ADP7104), and standalone vs. controlled mode setup requirements.

Technical Context

The EV-ADUM7701-8FMCZ implements a complete signal chain for evaluating the ADuM7701's isolated Σ-Δ modulator core, including galvanically separated analog (GND1) and digital (GND2) ground planes with 8 mm creepage/clearance. It integrates three regulated supplies: ADuM6000 (isolated 5 V for VDD1), ADP2360ACPZ-5.0 (buck regulator for high-voltage VDD1 sourcing via J7), and ADP7104ARDZ-5.0 (low-noise LDO for VDD2).

Interface flexibility is provided through dual operational modes: SDP-H1-controlled mode (via 160-pin connector and J9) and standalone mode (using J3 SMB for MCLK input and J4 SMB for MDAT output). Link configuration (LK1–LK8) determines supply routing, input grounding, and serial interface path - all validated per UG-1525 Rev. 0.

FAQ

What is the primary function of the EV-ADUM7701-8FMCZ evaluation board?

The EV-ADUM7701-8FMCZ evaluation board is a dedicated hardware platform for comprehensive characterization of the ADuM7701 isolated sigma-delta ADC. It provides regulated isolated power, configurable analog input paths, serial interface routing, and ACE software integration - enabling engineers to validate noise performance, linearity, timing behavior, and isolation integrity under real-world conditions. The EV-ADUM7701-8FMCZ does not operate as a standalone data acquisition system but requires connection to an EVAL-SDP-CH1Z controller board or external clock source.

Which controller board is required to operate the EV-ADUM7701-8FMCZ in standard mode?

The EV-ADUM7701-8FMCZ is designed to interface with the EVAL-SDP-CH1Z (SDP-H1) system demonstration platform controller board via its 160-way connector (J9). This connection supplies 12 V and 3.3 V rails, routes MCLK and MDAT signals, and enables USB-based communication with ACE software. Without the EVAL-SDP-CH1Z or equivalent FPGA-based host, the EV-ADUM7701-8FMCZ can only operate in limited standalone mode using external SMB clock and data capture tools - and even then, full ACE functionality remains unavailable.

Does the EV-ADUM7701-8FMCZ provide isolated power for both VDD1 and VDD2 rails?

Yes - the EV-ADUM7701-8FMCZ generates isolated power for VDD1 using the ADuM6000 isoPower dc-to-dc converter (5 kV isolation), while VDD2 is supplied either from the EVAL-SDP-CH1Z's 3.3 V rail or from the on-board ADP7104ARDZ-5.0 LDO (configured via LK2). Critically, VDD2 must not exceed 3.3 V when connected to the EVAL-SDP-CH1Z board to prevent permanent damage. The board also supports external high-voltage VDD1 sourcing (23–25 V via J7) using the ADP2360ACPZ-5.0 buck regulator.

How is analog input configured on the EV-ADUM7701-8FMCZ, and what are the voltage limits?

Analog input is applied differentially across J1 (VIN+) and J2 (VIN−), supporting a pseudo-differential range of ±250 mV (±320 mV full-scale). Jumpers LK7 and LK8 allow VIN+ and VIN− to be individually grounded for single-ended testing or offset calibration. Exceeding ±250 mV risks clipping or nonlinearity; the absolute maximum input is ±320 mV. Input signals must be referenced to GND1 (analog ground), which is physically isolated from GND2 (digital ground) with 8 mm creepage and clearance - a requirement verified in UG-1525 Figure 2 and Table 1.

Can the EV-ADUM7701-8FMCZ be used without installing ACE software?

No - ACE software is mandatory for functional operation of the EV-ADUM7701-8FMCZ in SDP-H1-controlled mode. The ACE software (with ADuM7701 plugin) provides register-level control, real-time data capture, and post-processing analysis (waveform, histogram, FFT). While basic power-up and signal injection can occur without ACE, no data readout, configuration, or performance evaluation is possible. The EV-ADUM7701-8FMCZ user guide explicitly states that ACE installation must precede hardware connection to ensure proper driver recognition and enumeration in Windows Device Manager.
