Analog Devices Inc. EVAL-AD5382SDZ

Overview

EVAL-AD5382SDZ from Analog Devices is a dedicated evaluation board for the AD5382BSTZ-5 - a 32-channel, 14-bit voltage-output DAC with on-chip reference and SPI/I²C/parallel interface support. It integrates an ADR421 2.5 V external reference, dual LDO regulators (ADP3331/ADP3367), and configurable link options for power, interface, and reference selection. Designed for rapid prototyping of precision analog output systems in industrial control and automated test equipment.

For engineers reviewing the EVAL-AD5382SDZ datasheet, EVAL-AD5382SDZ pinout, EVAL-AD5382SDZ application, or EVAL-AD5382SDZ equivalent, this page delivers verified hardware configuration details, SDP-B controller integration requirements, jumper-based interface mode selection (SPI vs. I²C vs. parallel), on-board reference routing options, and DAC output signal access via 40-way header J3 - all critical for lab validation and system-level bring-up.

Technical Context

The EVAL-AD5382SDZ implements full hardware support for the AD5382BSTZ-5's 32-channel 14-bit voltage DAC functionality, including configurable AVCC/DVCC sourcing (via LK1/LK2), REFOUT/REFIN selection (LK7), serial/parallel interface mode (LK9), and SPI/I²C protocol choice (LK10). It supports both SDP-B–controlled operation (via J10) and standalone digital control (via J1/J2).

Power delivery includes a 6 V input (J9) feeding two regulators to generate 5 V analog and digital supplies, or direct AVCC/DVCC injection via J7/J8. Output signals are accessible at J3 (VOUT0–VOUT31), J5 (VOUT0), and J6 (MON_OUT), with ground isolation maintained between AGND and DGND planes at a single point near U1.

FAQ

What is the primary function of the EVAL-AD5382SDZ?

The EVAL-AD5382SDZ is a dedicated evaluation board for the AD5382BSTZ-5 32-channel, 14-bit voltage-output DAC. It provides complete hardware infrastructure-including power regulation, reference selection, interface configuration, and output signal access-to enable rapid functional validation, performance characterization, and system-level integration of the AD5382 in real-world applications. The EVAL-AD5382SDZ itself contains no active ICs beyond those required to support the AD5382.

Which interface modes does the EVAL-AD5382SDZ support for controlling the AD5382?

The EVAL-AD5382SDZ supports SPI (default, enabled by LK9=A and LK10=B), I²C (LK9=A and LK10=A), and parallel (LK9=B) interfaces for the AD5382. However, the official AD538x evaluation software supplied with the EVAL-AD5382SDZ only supports SPI communication. I²C and parallel modes require custom firmware or external logic control applied via J1 or J2 headers.

Can the EVAL-AD5382SDZ operate without the EVAL-SDP-CB1Z controller board?

Yes, the EVAL-AD5382SDZ can operate standalone. Digital control signals may be applied directly to Header J1 (7-pin) or Header J2 (28-pin), while analog and digital power supplies connect via J7 (AVCC) and J8 (DVCC). Link positions LK1 and LK2 must be set to Position B to select external supplies. This mode bypasses USB/PC control and requires user-provided timing and data signals.

How is the reference voltage configured on the EVAL-AD5382SDZ?

The EVAL-AD5382SDZ offers dual reference options: the internal AD5382 reference (1.25 V or 2.5 V) or the on-board ADR421ARZ 2.5 V external reference. Selection is controlled by jumper LK7: Position A connects J4 for external reference injection; Position B (default) routes the ADR421 output to the AD5382's REFOUT/REFIN pin. No soldering or component change is needed-only jumper repositioning.

What power supply configurations are supported by the EVAL-AD5382SDZ?

The EVAL-AD5382SDZ supports two power architectures: (1) Single 6 V input via J9 powers onboard ADP3331 (AVCC) and ADP3367 (DVCC) regulators - default for SDP-B use; (2) Independent AVCC (J7) and DVCC (J8) inputs - required for standalone operation. LK1 and LK2 must be set to Position B in the latter case. All supplies are decoupled with 10 µF tantalum + 0.1 µF ceramic capacitors.
