    Hello, have You any recomendations for power-up/power-down sequence for AD9273?
    

    I want to rise-up DRVDD first, then AVDD1 and AVDD2.
    

    For power-down: off all supplyes together.

      Hi Sanchogus,
      

      There is no power sequence requirement for AD9273, you can power up the DRVDD, AVDD1, AVDD2 at the same time.
      

      If you want to add the power up sequence, I will recommend you the below solutions.
      

      Only power sequence:  ADM1185 is easy to use.
      

      If you want power sequence and also power monitoring: ADM1068 is the candidate.
