Analog Devices Inc. EVAL-AD5667RSDZ

Overview

EVAL-AD5667RSDZ from Analog Devices is an evaluation board designed specifically for the AD5667R - a 16-bit, dual-channel, voltage-output digital-to-analog converter (DAC) with I²C interface, operating from a single 2.7 V to 5.5 V supply and featuring on-board ADR431BRZ ultralow-noise XFET reference. It supports PC-based control via the EVAL-SDP-CB1Z system demonstration platform (SDP) and enables rapid prototyping of precision analog output circuits in industrial and test instrumentation.

For engineers reviewing the EVAL-AD5667RSDZ datasheet, EVAL-AD5667RSDZ pinout, EVAL-AD5667RSDZ application, or EVAL-AD5667RSDZ equivalent, this page delivers verified hardware configuration options, SDP interface requirements, on-board power regulation (ADP7102 LDO), I²C address selection (via LK4), and DAC register control logic - all essential for functional validation and firmware integration.

Technical Context

The EVAL-AD5667RSDZ implements direct hardware interfacing between the AD5667R DAC and the EVAL-SDP-CB1Z controller via a 120-way FPC connector (J1), supporting real-time register access and waveform generation through Analog Devices' ACE software. Power is supplied either through J3 (6 V–20 V, regulated by ADP7102ACPZ-R7) or J2 (external regulated VCC), with decoupling provided by 10 µF tantalum and 0.1 µF ceramic capacitors.

Board-level configurability includes jumper-selectable I²C address bits (LK4), LDAC/CLR GPIO sourcing (LK2/LK3), internal/external reference routing (LK5), and optional ADC monitoring paths (LK6/LK7) linking VOUTA/VOUTB to AD7992BRMZ-0. The AD5667R's dual 16-bit DAC channels are accessible via SMB jacks (VOUTA/VOUTB) and support independent power-down and high-impedance modes.

FAQ

Is EVAL-AD5667RSDZ compatible with the AD5663R device?

No, EVAL-AD5667RSDZ is not compatible with the AD5663R. While both boards share identical hardware layout and part number prefix, the EVAL-AD5667RSDZ is populated exclusively with the AD5667RBRMZ-1 (I²C interface), whereas the EVAL-AD5663RSDZ uses the AD5663RBRMZ-5 (SPI interface). The firmware and ACE plug-in for EVAL-AD5667RSDZ are configured for I²C register mapping and timing - using it with AD5663R would result in communication failure. Always verify the U5 device marking on the board.

What software is required to operate EVAL-AD5667RSDZ?

EVAL-AD5667RSDZ requires Analog Devices' Analysis Control Evaluation (ACE) software, version 1.22.0 or later. ACE provides graphical register access, DAC channel control, memory map editing, and real-time waveform generation. The installer includes SDP drivers and .NET Framework 4. The EVAL-AD5667RSDZ plug-in appears automatically in ACE after connecting the EVAL-SDP-CB1Z board - no additional firmware flashing or manual driver installation is needed for basic operation.

Does EVAL-AD5667RSDZ include an on-board voltage reference?

Yes, EVAL-AD5667RSDZ includes an on-board ADR431BRZ ultralow-noise XFET voltage reference (2.5 V, ±0.04% initial accuracy, 3.5 ppm/°C drift). It is routed to the AD5667R's REFIN pin via LK5. When LK5 is in Position A, the internal reference is enabled; Position B connects an external reference source. The ACE software allows enabling/disabling the internal reference independently of jumper position - critical for validating external reference performance.

Can EVAL-AD5667RSDZ be powered directly from a USB port?

No, EVAL-AD5667RSDZ cannot be powered directly from a USB port. It requires either a 6 V–20 V DC supply applied to J3 (regulated by ADP7102 LDO) or a well-regulated external VCC (2.7 V–5.5 V) applied to J2. The EVAL-SDP-CB1Z board draws power from USB but does not supply power to the EVAL-AD5667RSDZ - the two boards are electrically isolated for noise immunity. Attempting USB-only operation will result in no DAC output or unstable behavior.

What is the function of LK4 on EVAL-AD5667RSDZ?

LK4 configures the I²C slave address bits [A1:A0] of the AD5667RBRMZ-1. Position B sets both bits to 0 (address 0x0E), Position C sets both to 1 (address 0x0D), and no connection (NC) yields 10 (address 0x0C). This allows up to three EVAL-AD5667RSDZ boards to coexist on the same I²C bus without address collision. ACE software reads the physical jumper state at startup and adjusts register write commands accordingly - mismatched LK4 position and software expectation causes ACK failures.
