• ADuM1100: Disfunction - burning out

    We use ADuM-1100 iCouplers. Some of them burn out. They are pumping current
    from output supply. Can you tell me what can be the cause of this problem ?

    We tough to a too high output current (1mA). Is it possible ?


    There are a few things that…

  • ADUM1100: Different supply voltage

    Could I applied different supply voltage (ex. Vdd1=5V & Vdd2=3,3V) on ADuM1100?


    Although the units work at the voltages you describe, we have concluded that we
    cannot guarantee such performance over all temperature, supply voltage, and

  • ADuM1100: Overvoltage when the output is shorted out

    I am using magnetic isolators in an isolated gate drive circuit which is
    typically operated at around 20kv/µs.

    The data sheet for ADuM1100 says this is OK.

    However there is a strong possibility the output will be shorted out in which…

  • ADuM1100 glitch filter window vs. very narrow pulses

    Problem description:

    I have found that narrow pulses of about 5ns cause the output to respond to
    only one edge and produce a pulse of many hundreds of nanoseconds until the low
    frequency path corrects it.

    It happens on both polarities and it…

  • ADuM1100 vs ADuM110N


    ADuM110N is suggested as a pin2pin replacement for ADuM1100.

    The first one seems to have a feature which is not mentioned in the second's DS: fail-safe output.

    Does ADuM1100 provides any mechanism of setting the outputs to a certain value…

  • Noise filter on power line for ADuM1100

    Dear Sir.Madam,

    I have a question for your ADuM1100 i-coupler,

    Our customer is proceeding to pwb design to use ADuM1100.

    So as for the power supply,

    Should we put the LC filter on the power-line for switching noise reduction like return back to power…
