Analog Devices Inc. EVAL-AD5372EBZ

Overview

EVAL-AD5372EBZ from Analog Devices is a USB-enabled evaluation board for the AD5372 32-channel, 16-bit denseDAC, supporting full register-level control, dual reference selection (3 V or 5 V), and stand-alone operation via 20-pin header J3. It integrates ADR423 (3 V) and ADR435 (5 V) references, CY7C68013 USB microcontroller, and on-board power regulation for DVCC, VDD, and VSS.

For engineers reviewing the EVAL-AD5372EBZ datasheet, EVAL-AD5372EBZ pinout, EVAL-AD5372EBZ application, or EVAL-AD5372EBZ equivalent, this board enables rapid validation of multichannel DAC performance in precision analog output systems-especially where channel density, reference flexibility, and PC-based register programming are critical.

Technical Context

The EVAL-AD5372EBZ implements a complete hardware interface between a host PC (via USB Mini-B) and the AD5372 DAC, using the CY7C68013 USB microcontroller to generate SPI-compatible control signals (DIN, SCLK, SYNC, LDAC, CLR, RESET). It supports both synchronous register writes and individual channel updates with LDAC-triggered output update.

Reference selection is managed through jumper LK4 (positions A/B/C), enabling use of internal ADR423 (3 V), ADR435 (5 V), or external SMB-connected voltage. Power is supplied either via screw terminals (J2) for analog/digital rails or via USB (for interface logic only); DVCC requires +5 V, while VDD/VSS follow AD5372's specified supply range.

FAQ

What DAC models does the EVAL-AD5372EBZ support?

EVAL-AD5372EBZ is explicitly designed for the AD5372 but shares full pin compatibility and functional validation with the AD5370 (40-channel, 16-bit) and AD5373 (32-channel, 14-bit). All three devices use identical interface timing and register maps, allowing one board to evaluate the entire AD537x family without hardware modification.

Does EVAL-AD5372EBZ require external power when used with USB?

Yes - USB supplies only the CY7C68013 interface logic and push-button circuitry. The AD5372 itself requires separate analog and digital power: +5 V for DVCC (via J2 screw terminals), plus user-configurable VDD and VSS within the AD5372's specified range. USB power is not routed to the DAC or its reference circuitry.

How is reference voltage selected on EVAL-AD5372EBZ?

Reference selection is controlled by jumper LK4: position A selects the ADR423 3 V reference, position B selects the ADR435 5 V reference, and position C routes an external voltage applied to the EXT_REF SMB connector. By default, LK4 is set to position A (3 V), and both VREF0 and VREF1 pins share the same selected source.

Can EVAL-AD5372EBZ operate without a PC connection?

Yes - EVAL-AD5372EBZ supports stand-alone mode. Remove jumpers LK1 and LK3 to isolate USB-generated control signals, then drive DIN, SCLK, SYNC, LDAC, CLR, and RESET directly via the 20-pin J3 header. This enables integration with custom microcontrollers or DSPs for embedded system validation.

What software is provided with EVAL-AD5372EBZ?

EVAL-AD5372EBZ ships with Windows-based GUI software that supports register programming across all AD537x channels, offset DAC configuration, direct 24-bit writes, LDAC-triggered output updates, and real-time output voltage calculation based on current X/M/C register values and reference selection.
