Analog Devices Inc. EVAL-AD5767SD2Z

Overview

EVAL-AD5767SD2Z from Analog Devices is a fully featured evaluation board for the AD5767 16-channel, 12-bit voltage-output DAC, integrating the ADP5071 dual-output switching regulator to generate ±8 V/−22 V from a single 3.3 V supply and enabling DAC output ranges from −20 V to +6 V. It supports PC-based control via the EVAL-SDP-CB1Z system demonstration platform and ACE software, with on-board PMOD (J10) and SDP (J1) interfaces.

For engineers reviewing the EVAL-AD5767SD2Z datasheet, EVAL-AD5767SD2Z pinout, EVAL-AD5767SD2Z application, or EVAL-AD5767SD2Z equivalent, this page delivers verified hardware configuration options, jumper-controlled power routing (ADP5071 vs. bench supply), software-defined output range selection (−20 V to +6 V), and direct integration of ADR4525 2.5 V reference and buffered analog outputs - all essential for precision DAC validation in industrial and test equipment design.

Technical Context

The EVAL-AD5767SD2Z implements a complete signal chain for the AD5767BCBZ-WP WLCSP DAC, including decoupled AVDD/AVSS (−22 V/+8 V or external), AVCC (2.97–5.5 V), and VLOGIC (1.7–5.5 V) rails, with configurable link options (LK1–LK12) for reference source, power sequencing, and filter bypass. It supports both USB-hosted ACE GUI control and direct SPI via PMOD J10 (SYNC, SDIN, SDO, SCLK, RESET).

Power architecture includes LC-filtered ADP5071 outputs (bypassable via LK11/LK12), selectable 3.3 V rail filtering (J11/J12), and dual-supply flexibility: ADP5071 mode (3.3 V input only) or bench supply mode (J9 with AVDD/AVSS up to 34 V differential). Output monitoring is enabled via MUX_OUT and channel-specific headers (J2/J3 for VOUT0–VOUT15).

FAQ

What is the primary function of the EVAL-AD5767SD2Z evaluation board?

The EVAL-AD5767SD2Z evaluation board is a complete hardware platform for evaluating the AD5767 16-channel, 12-bit voltage-output DAC. It integrates power regulation (ADP5071), reference (ADR4525), buffering, and interface circuitry to enable rapid functional validation, output range testing (−20 V to +6 V), and register-level configuration of the EVAL-AD5767SD2Z target device without external support components.

How does the EVAL-AD5767SD2Z generate its bipolar supply rails?

The EVAL-AD5767SD2Z uses the ADP5071ACPZ switching regulator to generate +8 V and −22 V from a single 3.3 V input supplied via J12. These rails power the AD5767's AVDD and AVSS pins. Alternatively, external bench supplies can be connected via J9, supporting wider output ranges (e.g., −16 V to +14 V), provided the AVDD-to-AVSS differential remains ≤34 V as specified for the EVAL-AD5767SD2Z.

Which software is required to operate the EVAL-AD5767SD2Z?

The EVAL-AD5767SD2Z requires Analog Devices' ACE (Analysis, Control, Evaluation) software, which provides a graphical user interface for configuring the AD5767 registers, selecting output voltage spans, enabling dither, routing channels to MUX_OUT, and performing real-time DAC updates. ACE connects via USB through the EVAL-SDP-CB1Z board (J1) and includes dedicated plugin support for the EVAL-AD5767SD2Z.

Can the EVAL-AD5767SD2Z be powered without the ADP5071 regulator?

Yes. The EVAL-AD5767SD2Z supports bench power supply operation via terminal block J9, delivering separate AVDD and AVSS voltages. This bypasses the ADP5071 and enables full DAC output range coverage (e.g., −12 V to +14 V), subject to jumper configuration (LK4/LK5 set to Position A) and compliance with the AD5767's absolute maximum ratings. The 3.3 V rail for AVCC/VLOGIC remains supplied via J11 or J12.

What are the key configurable jumpers on the EVAL-AD5767SD2Z and their roles?

The EVAL-AD5767SD2Z features 12 link options: LK1–LK5 and LK7 select reference, logic, and analog supply sources; LK4/LK5 route AVDD/AVSS between ADP5071 and J9; LK6 controls ADP5071 sequencing; LK7 selects ADR4525 or external reference; LK8 enables ADP5071 connection to J12; LK9/LK10 adjust ADP5071 switching frequency and slew rate; LK11/LK12 bypass LC filters on ADP5071 outputs - all critical for optimizing noise, range, and stability per the EVAL-AD5767SD2Z use case.
