AD5790 Evaluation Board Software and Hardware


     I am currently evaluating AD5790, I noticed that in it's evaluation board there is an extra ADR445BRZ. May I know if there are any other device that uses the same part of the board simultaneously. For it's software, I noticed that the product description has a typographical error, it should show 20-Bit instead of 18-bit. Below are the images of AD5790 Evaluation Board Software and Hardware.


Thank you,                                                                                                                                                                                                                            Perryl

  • Hi Perryl,

    The idea of connecting two references in parallel was to improve the accuracy (taking into account that the ADR445 specifies 1ppm/°C (typ) tempco), but not very significant results were achieved.

    Analog Devices do not provide ultra-stable temperature controllable references, which would need to be obtained from another supplier if a 20-bit accuracy is desired.

    Thanks for letting us know about the typo on the Evaluation Board Software.
