EVAL-AD57XXARDZ

Family of Precision, Single-Channel output DACs

Overview

The EVAL-AD5780ARDZ facilitates fast prototyping of the AD5780 circuit, and can be substituted with either the AD5760 or AD5790, which must be ordered separately. Similarly, the EVAL-AD5781ARDZ and EVAL-AD5791ARDZ come with the AD5781 and AD5791 respectively.

The AD5790, AD5791, AD5760, AD5780 and AD5781 are a family of precision, single-channel voltage output DACs, with resolutions from 16-bits up to 20-bits. They offer guaranteed monotonic operation, and low nonlinearity (down to 0.5 LSB INL and DNL)

The evaluation boards provide an on-board -14 V and +14 V dual power supply. These evaluation boards also utilize external reference boards with an output voltage of +10 V and -10 V. The eval boards are connected to the carrier board through the Arduino Shield connector.

Features:

  • Precision, single-channel voltage output DACs

  • Resolution options from 16 bits to 20 bits

  • Guaranteed monotonic operation

  • Low integral and differential nonlinearity (down to 0.5 LSB INL and DNL, device dependent)

  • Buffered voltage outputs

  • Wide bipolar output voltage range support

  • External precision reference input

  • SPI-compatible serial interface

  • Low noise and low glitch performance

  • Industrial temperature range operation

Applications:

  • Medical instrumentation

  • Test and measurement equipment

  • Industrial control systems

  • Scientific instrumentation

  • Aerospace and defense instrumentation

  • Data acquisition systems

  • Precision DC sources

  • Digital gain and offset adjustment

  • Power supply control and calibration

Recommendations

People who follow the flow that is outlined, have a much better experience with things. However, like many things, documentation is never as complete as it should be. If you have any questions, feel free to ask on our EngineerZone forums, but before that, please make sure you read our documentation thoroughly.

To better understand the AD5790 /AD5791 /AD5760 /AD5780 /AD5781, we recommend to use the EVAL-AD5780ARDZ /EVAL-AD5781ARDZ /EVAL-AD5791ARDZ evaluation boards.
