Analog Devices Inc. EVAL-AD5676SDZ

Overview

EVAL-AD5676SDZ from Analog Devices is a dedicated evaluation board for the AD5676 octal, 16-bit voltage-output nanoDAC+ IC. It supports full register-level control via the EVAL-SDP-CB1Z system demonstration platform, provides on-board ADR431 2.5 V reference, accepts external reference via EXT_REF SMB connector, and delivers eight independent DAC outputs (VOUT0–VOUT7) for precision analog prototyping in industrial and test instrumentation applications.

For engineers reviewing the EVAL-AD5676SDZ datasheet, EVAL-AD5676SDZ pinout, EVAL-AD5676SDZ application, or EVAL-AD5676SDZ equivalent, this page delivers verified hardware configuration options, SDP-B interface requirements, ACE software integration details, link jumper settings (LK1–LK5), and power supply routing (J1–J3) essential for rapid functional validation of the AD5676 DAC family.

Technical Context

The EVAL-AD5676SDZ implements a complete hardware interface between a PC and the AD5676 16-bit octal DAC, using the EVAL-SDP-CB1Z controller board as the USB-to-SPI bridge. It routes all DAC control signals-including LDAC, RESET, SCLK, SDIN, and CS-through J4 (SDP-B connector) or J5 (standalone digital I/O header).

Power architecture includes dual regulated supplies: ADP3331 (U1) generates INT_VCC for analog circuitry, while ADP3367 (U3) provides VLOGIC; both are fed from a single 6 V input at J3. Link LK3 configures reference selection (ADR431 vs. external), and LK5 sets gain mode (0–VREF or 0–2×VREF), directly mapping to AD5676 register bits.

FAQ

What is the primary function of the EVAL-AD5676SDZ?

The EVAL-AD5676SDZ is a dedicated evaluation board for the AD5676 octal, 16-bit voltage-output DAC. It enables full register-level programming, output voltage validation, and timing behavior analysis of the AD5676ARUZ IC using the EVAL-SDP-CB1Z controller and ACE software. The EVAL-AD5676SDZ does not operate standalone-it requires the SDP-B board or compatible digital interface to drive the DAC's SPI interface and control signals.

Which DAC variant does the EVAL-AD5676SDZ support?

The EVAL-AD5676SDZ is configured for the AD5676 (non-reference version), as confirmed by its on-board ADR431BRZ reference IC and LK3 jumper default position B. It is mechanically and electrically compatible with the EVAL-AD5676RSDZ board but targets the AD5676ARUZ-not the AD5676RARUZ-which lacks an internal reference and relies on external or on-board reference sources. Both boards share identical layout and interface logic.

What software is required to operate the EVAL-AD5676SDZ?

The EVAL-AD5676SDZ requires Analog Devices' Analysis Control Evaluation (ACE) software, which provides GUI-based register editing, memory map access, real-time DAC output control, and block diagram visualization. ACE installs SDP drivers and .NET Framework 4 automatically and recognizes the EVAL-AD5676SDZ plug-in upon connection. No third-party or custom firmware is needed-the EVAL-AD5676SDZ operates exclusively through ACE's native AD5676 device profile.

How is power supplied to the EVAL-AD5676SDZ?

The EVAL-AD5676SDZ accepts power via three configurable inputs: J3 (6 V dc main supply), J2 (external analog VCC), and J1 (external digital VLOGIC). In standard SDP-B–based operation, only J3 is used-the ADP3331 and ADP3367 regulators onboard generate INT_VCC and VLOGIC for the AD5676 and SDP interface. J1/J2 are reserved for advanced use cases where isolated or customized supply rails are required.

What are the key jumper (LK) functions on the EVAL-AD5676SDZ?

The EVAL-AD5676SDZ uses five link jumpers: LK1 selects analog supply (INT_VCC or EXT_VCC); LK2 selects digital supply (SDP-B V_IO or EXT_VLOGIC); LK3 selects reference (ADR431 or EXT_REF); LK4 sets power-up scale (zero or midscale); and LK5 configures gain (software-controlled, 0–VREF, or 0–2×VREF). These links directly map to AD5676 register bits and must be set before power-on to ensure correct DAC initialization and output behavior.
