Analog Devices Inc. EVAL-AD5764REBZ

Overview

EVAL-AD5764REBZ from Analog Devices is a full-featured evaluation board for the AD5764R quad-channel, 16-bit, bipolar voltage digital-to-analog converter (DAC), supporting ±10 V output span, on-board 5 V reference, and integrated temperature-sensing ADC. It enables rapid functional validation of DAC performance, gain/offset calibration, and serial interface behavior in lab and design verification environments.

For engineers reviewing the EVAL-AD5764REBZ datasheet, EVAL-AD5764REBZ pinout, EVAL-AD5764REBZ application, or EVAL-AD5764REBZ equivalent, this board supports USB-based PC control via CY7C68013A microcontroller, J21 header access to all AD5764R signals (SYNC, SCLK, SDIN, SDO, LDAC, CLR), configurable link options for analog/digital supply routing and coding format selection (binary/twos-complement), and real-time core temperature monitoring.

Technical Context

The EVAL-AD5764REBZ implements direct USB 2.0 connectivity using a Cypress CY7C68013A-56LFCX controller, enabling Windows-compatible software-driven register read/write, function configuration, hardware setup, and calibration. All four DAC outputs (VOUTA–VOUTD) are accessible via SMB connectors and test points, with independent short-circuit protection selectable per LK2 (500 µA to 10 mA).

Power architecture separates analog (AVDD/AVSS: ±11.4 V to ±16.5 V) and digital (5 V or 3.3 V via LK1/LK7) domains, with AGND/DGND connected at a single point near U4 (AD5764RCSUZ) to minimize ground loops. Reference selection (internal ADR02BRZ or on-board 5 V) is controlled by LK4, while REFAB/REFCD routing is managed by LK5.

FAQ

What is the primary purpose of the EVAL-AD5764REBZ?

The EVAL-AD5764REBZ is an evaluation board designed exclusively for functional and performance validation of the AD5764R quad-channel, 16-bit, bipolar voltage DAC. It provides complete signal access, calibrated reference, temperature monitoring, and PC-based software control - not for production use. The EVAL-AD5764REBZ enables engineers to verify DAC linearity, settling time, crosstalk, and serial interface timing before integrating the AD5764R into final systems.

Does the EVAL-AD5764REBZ support external analog reference inputs?

Yes, the EVAL-AD5764REBZ supports external reference inputs via J3 (REFAB) and J4 (REFCD). Link LK5 determines whether the on-board 5 V reference or internal ADR02BRZ is routed to those pins; inserting only Position A connects REFCD, while only Position B connects REFAB. External references must comply with AD5764R specifications: 4.5 V to 5.5 V, low noise, and sufficient drive capability.

How is the EVAL-AD5764REBZ powered, and what are the supply requirements?

The EVAL-AD5764REBZ requires three independent supplies: 5 V (digital, optionally sourced from USB via LK1-A), +11.4 V to +16.5 V (AVDD), and −11.4 V to −16.5 V (AVSS). DGND and AGND are internally joined at one point near U4; external systems must avoid additional AGND–DGND connections to prevent ground loops. Decoupling uses 10 μF + 0.1 μF per supply rail.

Can the EVAL-AD5764REBZ operate without a PC connection?

Yes, the EVAL-AD5764REBZ can operate without a PC when LK11 is set to Position A, enabling external control via J21 or SMB connectors. All AD5764R interface signals - including SYNC, SCLK, SDIN, SDO, LDAC, CLR, BIN/2sCOMP, RSTIN, and D0/D1 - are exposed and fully accessible. Power sequencing and link configurations (e.g., LK7 for 3.3 V/5 V logic, LK2 for short-circuit current) must be manually verified per application needs.

What software tools are provided with the EVAL-AD5764REBZ?

The EVAL-AD5764REBZ ships with Windows-compatible evaluation software that supports register-level read/write, function register configuration (SDO enable, Local Gnd Offset Adjust), hardware pin state setup (LDAC, CLR, BIN/2sCOMP), core temperature measurement, and per-channel offset/gain calibration. Software installation requires Windows 2000/NT/XP and runs from included CD; no drivers beyond standard USB CDC are needed for CY7C68013A communication.
