AD5110 Power-On Reset

Hello All,


I have some questions for AD5110 Power-On Reset.


Q1) What is the threshold voltage value for POR?

And which pin’s voltage level does monitor for? VLOGIC or both VLOGIC and VDD?

(Please see the attached picture for your reference)


Q2) What’s the POR behavior at the time when the voltage is falling down such as the temporary blackout?


Best Regards,

  • Hi Tak,

    Apologies for the delay, I need to get one of our designers to investigate your query. I'll get back to you as soon as I can.

    Out of interest, what voltage do you anticipate your supply will drop to?

    Kind Regards,


  • Hi DRice,

    I really appreciated your confirmation.

    Honestly, there is no voltage value has been pointed out from my customer.

    My customer had some experience using the competitor’s device (not ADI).

    Issue is that after the temporary blackout and then, back to within specified voltage, but device was not normal operation.

    Thank you very much for considering my request.

    Best Regard,
