Evaluation Board for AD5443, AD5446, and AD5453 DACs (UG-327)
User guide for evaluating AD5443, AD5446, and AD5453 current output DACs using the EV-AD5443/46/53SDZ evaluation board and System Demonstration Platform (SDP).
Overview
This user guide describes the evaluation board for the AD5443 (12-bit), AD5446 (14-bit), and AD5453 (14-bit) CMOS current output digital-to-analog converters. The EV-AD5443/46/53SDZ board connects to the EVAL-SDP-CB1Z system demonstration platform via a 120-pin connector to provide USB-to-SPI communication. The document details the implementation of the on-board ADR01 voltage reference and AD8065 precision amplifier for current-to-voltage conversion. It includes instructions for the LabVIEW-based graphic user interface, board schematics, and layout diagrams for evaluating features like 4-quadrant multiplication and daisy-chaining.
Use Cases
- Automatic test equipment
- Instrumentation
- Digitally controlled calibration
- Digital waveform generation
- Analog processing
