  • Hi Doug,

     

    Let me ask this question again.

    One of our customer said that AD9609 become really hot when AVDD is turned off and DRVDD is applied.

    (They told us that they can't touch the device due to the heat, probably over 70℃)

    Could you double check if there is a power sequence?

    (They are worried if there is a leak pass on the device)

     

    Best regards,
