Analog Devices Inc. EVAL-AD5380SDZ

Overview

EVAL-AD5380SDZ from Analog Devices is a full-featured evaluation board for the AD5380BSTZ-5 - a 40-channel, 14-bit voltage-output DAC with on-chip reference and 2.5 V/5 V output span capability. It integrates an ADR421 2.5 V external reference, dual LDO regulators (ADP3331/ADP3367), SPI interface support via EVAL-SDP-CB1Z, and configurable link options for power, interface mode, and reference selection. Designed for rapid prototyping of precision analog output systems in industrial control and automated test equipment.

For engineers reviewing the EVAL-AD5380SDZ datasheet, EVAL-AD5380SDZ pinout, EVAL-AD5380SDZ application, or EVAL-AD5380SDZ equivalent, this page delivers verified hardware configuration details, jumper setup logic, SDP-B interface requirements, software compatibility (Windows XP/Vista/7, 32-/64-bit), and DAC register-level control capabilities - all specific to the shipped EVAL-AD5380SDZ board populated with AD5380BSTZ-5.

Technical Context

The EVAL-AD5380SDZ implements a complete signal chain for evaluating the AD5380BSTZ-5 DAC: it accepts 6 V input via J9 and generates regulated 5 V AVCC/DVCC supplies using ADP3331 (analog) and ADP3367 (digital); supports both SDP-controlled (J10) and standalone operation (J1/J2 headers); and provides flexible reference routing via LK7 between internal DAC reference and external ADR421 2.5 V source.

Interface configuration is managed through 12 jumpers (LK1–LK12): LK9/LK10 select serial (SPI/I²C) vs. parallel mode and SPI vs. I²C; LK12 controls daisy-chain enable/disable; LK6 sets normal vs. power-down mode; LK3–LK5 configure LDAC/CLR/RESET logic levels; and LK7/LK8 determine reference source and FIFO enable state - though FIFO is disabled by default and unsupported by included software.

FAQ

What is the primary device evaluated by the EVAL-AD5380SDZ?

The EVAL-AD5380SDZ evaluates the AD5380BSTZ-5 - a 40-channel, 14-bit voltage-output DAC with on-chip reference and 2.5 V/5 V output span. The board is pre-populated with this exact IC, as confirmed in the UG-757 user guide General Description section and Bill of Materials. All hardware design, jumper configurations, and software functionality are optimized specifically for the AD5380BSTZ-5 variant.

Does the EVAL-AD5380SDZ support I²C or parallel interface operation?

The EVAL-AD5380SDZ hardware supports I²C and parallel modes via jumper settings (LK9/LK10 for I²C; LK9 Position B for parallel), but the included AD538x Evaluation Software only supports SPI communication. Per UG-757 Section "Link Configuration Options", LK10 defaults to Position B (SPI mode), and the software documentation explicitly states "Only the SPI interface is supported by the software." I²C and parallel use require custom firmware.

What power supply configuration is required when using the EVAL-SDP-CB1Z controller?

When used with the EVAL-SDP-CB1Z, the EVAL-AD5380SDZ requires a single 6 V DC supply connected to Connector J9. This powers both the evaluation board and the SDP-B via on-board regulators (ADP3331 and ADP3367). LK1 and LK2 must be in Position A to route regulated 5 V AVCC/DVCC to the AD5380BSTZ-5, as specified in Table 2 and the Power Supplies section of UG-757.

Can the EVAL-AD5380SDZ operate without the EVAL-SDP-CB1Z board?

Yes - the EVAL-AD5380SDZ supports standalone operation. Digital control signals can be applied directly to Header J1 or J2, and analog/digital power supplies can be connected via J7 (AVCC) and J8 (DVCC). In this mode, LK1 and LK2 must be set to Position B to bypass on-board regulators and accept external supplies, per UG-757 Section "Evaluation Board Hardware".

Is the FIFO function enabled and supported on the EVAL-AD5380SDZ?

No - the FIFO function is disabled by default (LK8 in Position B) and is not supported by the supplied AD538x Evaluation Software. UG-757 Section "Link Configuration Options" states: "The software supplied with the AD5380/AD5382 evaluation board does not support FIFO operation." Enabling FIFO via LK8 would require custom driver development and is not validated for use with this evaluation kit.
