• ADUM7442 minimum input frequency

    The datasheet for ADUM7442 has the following statement:

    "If the decoder receives no internal pulses of more than approximately 5 μs, the input side is assumed to be unpowered or nonfunctional, in which case the isolator output is forced to a default…

  • Circuit review of ADUM7442

    Hellow,

    My customer got a problem  at ADUM7442.

    They have used ADUM7442 in their system and they find some ADUM7442 aren't operated.

    (Sometimes they find that the output of pin 6 (U12) isn't operated normally.

      And after replacing to other ADUM7442…

  • Test data ADuM7442S regarding SEE

    Dear analog devices Team,

    i wanted to use your space isolator ADuM7442S.

    I already checked the TID test data you provide on your homepage. Do you also have tests/ test data regarding single event effects, e.g. SEU, SEL? If yes, can you provide the…

  • ADuM7442S Digital Isolator Output State at Power On

    To Whom it May Concern,

    In regards to the ADuM7442S Digital Isolator. Is there a guaranteed state at the outputs at Power On?

    The scenario is that the Input Side is powered, and the Output Side just becomes powered (the Power On Event), are the Outputs…

  • RE: LTM2881 and LTM2882 in Space Applications

    Hi Ryan,

    Unfortunately these products are not on our space qualified parts list. For isolation I would suggest ADuM7442S or ADuM141ES, both of which are quad channel isolators that are already space qualified.

    We have a complete list of space qualified…

  • Unpower one side on ADUM744X

    Hi,

    I was wondering if it was dangerous for the ADUM to unpower one side? All inputs on the unpowered side are connected by a pull down resistor and will not have any signal on it.

    Thanks
