Analog Devices Inc. EVAL-AD5590EBZ

Overview

EVAL-AD5590EBZ from Analog Devices is a USB-enabled evaluation board for the AD5590 16-channel, 12-bit multichannel I/O port IC. It supports standalone microcontroller/DSP control via 20-pin J1 header and provides full register access to DACs, ADCs, internal references, and power management features. Designed for rapid prototyping of mixed-signal industrial and instrumentation systems.

For engineers reviewing the EVAL-AD5590EBZ datasheet, EVAL-AD5590EBZ pinout, EVAL-AD5590EBZ application, or EVAL-AD5590EBZ equivalent, this page delivers verified hardware configuration details, USB/software operation constraints, reference selection options, power supply link settings, and standalone interface signal mapping - all essential for lab validation and system integration planning.

Technical Context

The EVAL-AD5590EBZ implements a complete test platform for the AD5590BBCZ, integrating CY7C68013A-56LFXC USB microcontroller for PC communication and SN74HC245PWR bus transceivers for level-shifting. It supports dual internal 2.5 V references (VREFIN1/VREFOUT1 and VREFIN2/VREFOUT2), selectable via LK16, and provides independent analog input (VIN0–VIN15) and output (VOUT0–VOUT15) test points with series grounding links.

Power architecture includes four dedicated 5 V supply connectors (J3–J6), configurable via six solder-jumpers (LK33–LK37) to consolidate supplies or enable USB-only operation (LK35 in Positions A+B). Standalone mode disables USB interface signals by removing LK38 and routes DSYNC1/DSYNC2, DSCLK, DDIN, LDAC, CLR, ASCLK, ASYNC, ADIN, and ADOUT through J1.

FAQ

What is the primary function of the EVAL-AD5590EBZ?

The EVAL-AD5590EBZ is a dedicated evaluation board for the AD5590BBCZ multichannel I/O port IC. It enables functional verification and performance characterization of all 16 DAC channels, 16 ADC channels, internal references, and digital interface timing. The board is not intended for production use but serves as a validated hardware platform for lab-based design exploration and firmware development targeting the AD5590.

Can the EVAL-AD5590EBZ operate without a PC connection?

Yes, the EVAL-AD5590EBZ supports standalone operation. By removing jumper LK38 and configuring power links (LK33–LK37 per Table 3), the board isolates the USB interface and exposes the AD5590's native parallel digital interface on 20-pin header J1. This allows direct control from an external DSP or microcontroller using signals including DSYNC1/DSYNC2, DSCLK, DDIN, LDAC, CLR, ASCLK, ASYNC, ADIN, and ADOUT - as defined in Table 5 of the board documentation.

How are reference voltages selected on the EVAL-AD5590EBZ?

Reference selection is controlled by 3-position jumper LK16. Position B connects VREFIN1/VREFOUT1 to VREFA; Position C connects VREFIN2/VREFOUT2 to VREFA; Position A selects an external reference applied to the VREF SMB jack. Both internal references are 2.5 V ± 0.5%, and only one should be enabled at a time when linked together to avoid contention - a constraint explicitly noted in the software section regarding simultaneous reference activation.

What power supply configurations does the EVAL-AD5590EBZ support?

The EVAL-AD5590EBZ accepts up to four independent 5 V supplies via connectors J3 (AMP0–AMP3), J4 (AMP4–AMP7), J5 (ADC/DAC core), and J6 (VDRIVE). Power grouping is achieved using solder jumpers LK33–LK37: LK35 in both Positions A and B enables full USB-only operation; LK36 connects V2− to AGND for single-supply op amp use; LK37 selects AVDD or external source for VDRIVE. Configuration details are documented in Tables 1–3 of the board user guide.

Does the EVAL-AD5590EBZ include software, and what functions does it provide?

Yes, the EVAL-AD5590EBZ ships with PC software (distributed on CD) that communicates via USB to program AD5590 registers, read all 16 ADC channels, and write to all 16 DAC channels. The GUI features tabbed interfaces for DAC blocks (0–7 and 8–15), ADC configuration (input range, ADOUT weak/three-state), and Misc controls (LDAC/CLR state, raw register writes). It also supports saving 512 ADC samples per channel to file, though sample timing depends on Windows OS scheduling.
