Analog Devices Inc. EVAL-AD5758SDZ

Overview

EVAL-AD5758SDZ from Analog Devices is a full-featured evaluation board for the AD5758 - a single-channel, 16-bit voltage and current output DAC with dynamic power control (DPC), HART connectivity, and integrated diagnostics. It supports ±10 V, 0–10 V, 4–20 mA, and 0–20 mA output ranges, operates from −33 V to +33 V supply rails, and interfaces via SPI through the EVAL-SDP-CS1Z system demonstration platform.

For engineers reviewing the EVAL-AD5758SDZ datasheet, EVAL-AD5758SDZ pinout, EVAL-AD5758SDZ application, or EVAL-AD5758SDZ equivalent, this page delivers verified hardware configuration options, ACE software integration details, isolated power management architecture, DPC-enabled thermal optimization, and HART-compliant analog output validation - all critical for industrial process control prototyping and functional safety validation.

Technical Context

The EVAL-AD5758SDZ implements a complete signal chain around the AD5758 DAC, including on-board ADR4525 2.5 V reference, ADP1031-1 isolated PMU generating AVDD1 (+26.7 V), AVDD2 (+5.15 V), and AVSS (−15.4 V), plus VLDO-derived 3.3 V VLOGIC. All digital signals (SPI, RESET, LDAC, FAULT) are isolated via the ADP1031-1's integrated signal isolation channels.

Hardware configurability is achieved through 13 jumper links (JP1–JP13) and dual-position switches (S2, P10) enabling unipolar/bipolar output mode selection, reference source routing (ADR4525 vs. AD5758 REFOUT), dc-to-dc bypass (JP6), address pin strapping (JP7/J8), and SDP-S disconnection for external controller interfacing - supporting both lab evaluation and embedded system integration workflows.

FAQ

What is the primary function of the EVAL-AD5758SDZ evaluation board?

The EVAL-AD5758SDZ evaluation board is a fully configured hardware platform for evaluating the AD5758 single-channel, 16-bit voltage and current output DAC. It enables rapid validation of dynamic power control, HART-compatible analog outputs, diagnostic features, and SPI-based configuration - all without requiring custom PCB design. The EVAL-AD5758SDZ integrates isolated power, precision reference, and ACE software support to replicate real-world industrial actuator and transmitter use cases.

Which companion hardware is required to operate the EVAL-AD5758SDZ?

The EVAL-AD5758SDZ requires the EVAL-SDP-CS1Z system demonstration platform (SDP-S) to interface with a PC via USB. The SDP-S provides isolated SPI communication, RESET and LDAC control, and FAULT monitoring. Without the EVAL-SDP-CS1Z, the EVAL-AD5758SDZ cannot be powered or controlled via ACE software - though it supports external controller connection via P10 link removal and JP4/S2 reconfiguration.

Does the EVAL-AD5758SDZ support HART communication out of the box?

Yes - the EVAL-AD5758SDZ supports HART communication through the AD5758's integrated HART modulation capability. The board includes CHART and C_HART components for HART signal coupling, and the ACE software exposes the HART_EN bit in the General-Purpose Configuration 1 register. Enabling HART_EN allows the AD5758 to superimpose digital HART signals onto its 4–20 mA analog output - validated per HART Physical Layer Specification.

How is power isolation implemented on the EVAL-AD5758SDZ?

Power isolation on the EVAL-AD5758SDZ is implemented using the ADP1031-1 isolated PMU, which provides reinforced galvanic isolation between primary (digital/USB) and secondary (analog/DAC) domains. It generates AVDD1 (+26.7 V), AVDD2 (+5.15 V), AVSS (−15.4 V), and VLDO-derived 3.3 V VLOGIC - all referenced to isolated ground planes (PGND_ISO, AGND). This architecture meets IEC 61000-4-5 surge immunity requirements and prevents ground-loop interference in industrial installations.

Can the EVAL-AD5758SDZ be used for production-level testing beyond lab evaluation?

Yes - the EVAL-AD5758SDZ is designed for both lab evaluation and production-grade validation. Its on-board ADR4525 reference, ADP1031-1 isolated power, configurable jumpers for rail selection and output mode, and ACE software's register-level diagnostic readback (digital/analog diagnostic registers) enable repeatable, traceable testing of DAC linearity, thermal drift, fault response, and HART interoperability - meeting requirements for IEC 61511 functional safety verification and field device certification.
