    Is there Spice-Model for ADuM4121-1? I've tried with help of "IBIS2SPICE" the IBIS Model transfered into Spice-Model. However, there is still a Problem, when I use the Spice-Model in LT-Spice, the Model can not be recognized. …
  • ADuM4121 IBIS Moel or SPICE Model

    My customer is seeking the IBIS model or SPICE model of ADuM4121.
    I looked up the ADuM4121 product page and found an IBIS model.
    However, there is only inputbuffer in this model.

    I searched for "Engineer zone", but I could not find the answer.…

  • RE: ADUM4121-1BRIZ Gate Driver


    The ADuM4121-1 is intended to be used as a gate driver. The gates it is intended to drive are capacitive in nature, like MOSFET and IGBT gates, where once the gate charge is delivered, the gate driver doesn't need to provide more current. The…

  • (ADuM4121)How fast can ADuM4121 detect mirror Clamp?

    Hi !

    I was reading ADuM4121 datasheet.

    I understood that ADuM4121 can detect mirror clamp at 2V.

    So my questions are these.


    Is it possible to change threshold voltage?

    I think for GaN, 2V is too high.


    If the Vclamp goes lower than 2V, how fast…


    Hi !

    I have a question about ADuM4121.

    Does this means 

    "User can input more than 50ns pulse"


    "ADuM4121 can output 50ns minimum pulse2


    Best regards


  • RE: Question about ADuM3221A

    Hello Kazu,

    The schematic you have drawn is correct, and a possible implementation of driving GaN. I don't recommend using the ADuM3221, though, for a few reasons:

    1) The CMTI is only 25 kV/µs, and GaN usually switches at a very fast slew rate

  • ADUM4121 Peak Current


    I have a question ADUM4121.

    Figure17 is Peak Output Current.

    Is it  also no problem by this Figure17 current ?
