  • Compliance of IEC61010-1 and VDE0884-10

    Hello,

     

    I am confused about the safety ratings of the part ADuM4120. Its datasheet states reinforced insulation for a working voltage of 400Vrms to meet IEC61010-1, while the rating for reinforced insulation with VDE0884-10 is 849Vpeak.

     

    According…

  • (ADuM4120)How did you improve isolation voltage?

  • 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

  • RE: ADuM4122

    Thank you  RSchnell,  

      My mistake R2 connection, the idea was to put R2 in series to gate´s.to see SR control.

       I see, ADuM4120 seem a better option.

    Thank you.

  • RE: ADUM3123 Fsw maximum question?

    Hello,

    The ADuM3123 is capable of operating at 6.78 MHz, but there will be significant self heating within the IC. The ADuM3123 also has a minimum pulse width of 50 ns, so if the design requires pulses shorter than that, there may be an issue.

    The ADuM3123…
