Clarification in ADS1247IPW

Hi,

We are going to implement ADS1247IPW application in our design. I have a query in its power supply. Please confirm do we need power up sequence between AVDD and DVDD?

Thanks in advance.

    Logesh,


    When the device was first introduced, there were specific guidelines on power up sequencing. Shortly afterward, we made some modifications to the power-on-reset circuitry. We've since removed that section of the datasheet, and feel that the power-up should be robust regardless of sequencing.

    However, if you are still concerned about this, you can toggle the reset pin of the device after the power-up.
