Pin voltage tolerance of Tout on ADM3252E

Hi everyone, I'm looking for the recommended voltage range that the Tout pin on ADM3252E can tolerate. I'm guessing the value given in the "Absolute Maximum Ratings" section (+/-15V) is meant to be that rating, but the way it's labelled ("Output voltages") has left me uncertain if that's actually what I'm looking for. So my question is what is the recommended (not abs. maximum) voltage that the Tout pin can tolerate on that part? And if it's indeed +/-15V, I just wanted to confirm that I understood that correctly. Thanks for reading!

    Hi Agromov,

    Abs max rating on the Tout pins is +/-15V.

  • Hi Naveen, thanks for the reply. Often there will be the absolute maximum range and the recommended range for these types of ratings. The implication is that reaching the abs. maximum limit won't critically damage the part, but it will decrease the lifetime of the part. Does AD make this distinction for this part? Thanks!

    Hi Agromov,

    It's always a good idea to stay below the abs max ratings. That's why they are there. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to them. Abs max is usually a stress rating;  Functional operation of this part at these ratings is not implied above the operating range given in the spec. We mostly say that the part can tolerate this, but exposure to absolute maximum rating conditions for extended periods may affect device reliability like you said. If you're worried about ESD events then that's a different thing. We usually have TVS diodes there to protect those pins against surge events.
