Analog Devices Inc. EVAL-AD5504EBZ

Overview

EVAL-AD5504EBZ from Analog Devices is a fully featured evaluation board designed to validate the AD5504BRUZ quad-channel, 12-bit, high-voltage voltage-output DAC in system-level applications. It supports both USB-connected PC operation and standalone control via a 10-pin header (J6), delivers up to 60 V DAC outputs across four SMB connectors (T1–T4), and includes on-board power regulation, EEPROM, and USB microcontroller (Digi-Key 428-1669-ND).

For engineers reviewing the EVAL-AD5504EBZ datasheet, EVAL-AD5504EBZ pinout, EVAL-AD5504EBZ application, or EVAL-AD5504EBZ equivalent, this page provides verified functional context, interface configuration options (USB vs. standalone), power supply routing (VLOGIC 2.7–5 V, VDD user-defined), DAC output access method, and software-controlled register programming capability.

Technical Context

The EVAL-AD5504EBZ implements a hardware abstraction layer between a host PC (via USB Mini-AB) and the AD5504BRUZ DAC, translating USB commands into SPI-compatible control signals (CLR, SYNC, SCLK, SDI, LDAC) routed through configurable jumpers (LK1, LK10). It supports dual operational modes: USB-hosted register programming using Analog Devices' proprietary PC software, or direct microcontroller/DSP interfacing via J6 header with three-stateable control lines.

Power architecture separates logic (VLOGIC, selectable via LK9: 3.3 V from ADP3303ARZ-3.3, 5 V from USB, or external) from analog (VDD, user-supplied via banana jacks J2–J5). High-voltage safety is enforced by included perspex covers, mandatory for operation due to 60 V DAC output capability.

FAQ

What is the primary function of the EVAL-AD5504EBZ?

The EVAL-AD5504EBZ is an evaluation board that enables full functional and performance validation of the AD5504BRUZ quad-channel, 12-bit, high-voltage DAC. It provides USB-based register programming via PC software and standalone SPI-compatible control via its 10-pin J6 header. The EVAL-AD5504EBZ does not replace the AD5504BRUZ in production but serves exclusively as a development and characterization tool for the AD5504BRUZ.

Does the EVAL-AD5504EBZ support both AD5501 and AD5504 devices?

Yes - the EVAL-AD5504EBZ is a shared platform supporting both the AD5501BRUZ (single-channel) and AD5504BRUZ (quad-channel) DACs. Hardware configuration differs per device: AD5504 uses all four SMB outputs (T1–T4), while AD5501 uses only T1. The board's software presents a selection screen to configure registers and controls appropriately for either device, and the Bill of Materials confirms U1 is populated with AD5504BRUZ for this specific variant.

How is power supplied to the AD5504BRUZ when using the EVAL-AD5504EBZ?

The AD5504BRUZ on the EVAL-AD5504EBZ receives two independent supplies: VLOGIC (2.7–5 V) selected via jumper LK9 (3.3 V regulator, USB 5 V, or external source), and VDD (user-defined, within AD5504BRUZ specs) applied via banana jacks J2–J5. USB power powers only the interface circuitry (U2), not the DAC itself - ensuring clean, isolated analog supply paths critical for high-voltage DAC accuracy and noise performance.

Can the EVAL-AD5504EBZ operate without a PC connection?

Yes - the EVAL-AD5504EBZ supports true standalone operation. Removing jumper LK1 disconnects USB-generated control signals (CLR, SYNC, SCLK, SDI, LDAC), enabling external microcontroller or DSP to drive the AD5504BRUZ directly via the 10-pin J6 header. Pinout details (e.g., Pin 1 = CLR, Pin 2 = SYNC) are documented in Table 1 of UG-059, and LK10 position determines R_SEL logic level for proper channel selection during standalone use.

What safety precautions are required when using the EVAL-AD5504EBZ?

Due to the AD5504BRUZ's capability to generate up to 60 V output, the EVAL-AD5504EBZ ships with mandatory perspex covers installed on both top and bottom layers. These covers must remain in place during all operation to prevent accidental contact with high-voltage traces or components. Removal voids safety compliance and risks electric shock - a requirement explicitly stated in Section 3 (Safety Requirements) of UG-059.
