• ADuM3482  ground separation

    Hi, I I'm looking for a suggestion how to separate isolated grounds...

    My design requires 4 isolated lines, two IN, two OUT and GND connected to the DB-9 connector. Side 1 (FPGA) has a 1.8V level and the other side 2 (ext interface) is required 3…

  • CTRL Pins on ADuM3482

    Q 

    Please can you explain the consequence of logic level signals applied to pins 7
    & 14 of the ADUM3482.

     

    A 

    So the CTRL pins of the ADuM3482 controls the default high or low for each side.

    CTRL1 controls the default state for side…

  • Possible issue with Adum3482

    Hi,

    We designed several Adum3482 into a product and found to our surprise that the VDDL1 pin can power our entire board -- with current flowing out of pin 1.

    Schematic fragment here.

    All IO is 3.3V, and I assumed that the best way of using this was…

  • adum3482 optoisolator and power pin permutation query

    Q 

    Can one use different voltage permutation wrt Adum3482 isolated pins, i.e.
    VDD1,VDDL1 5V and VDD2,VDDL2 3.3V ? With logic 1 on VIx i have a logic 1 on
    VOx (no inversion) ? I don't understand the CTRL function.

  • RE: Some Questions for AD5700 HART device

    Hi Kaos,

    In other word, can the CN0267 circuit communicate as Tx and Rx?

    If so, 8ch are made from 8 x CN0267s, correct?

     

    You will need 8 x AD5421's or 2 x AD5755-1 (if application is group isolated not ch-ch isolated).

    You could either use 8…
