• ADuM1400

    Q 

    Is it possible to use ADuM1400 in IGBT transistors gate control in asynchronous
    induction motor control circuit? Will the ADuM have tolerance to EMI?

     

    A 

    The ADuM1400 can indeed be used from an EMI point of view.  I think the
    customer would…

  • ADuM1400: Absolute maximum ratings

    Q 

    We use ADuM1400 in mix 3V/5V mode. Please inform me about max rating of signal
    Ve2 relative to GND2 and Vdd2.

     

    A 

    Ve2 has to be greater than  -0.5 and less than Vdd2+0.5V.  These voltage are
    referenced to GND2.

  • ADuM1400 & ADuM3400 ESD HARDENED

    Hi

    A customer asks me about the ADuM3400.

    The ADuM3400 is said to have better ESD immunity in the system than the ADuM1400.
    (By ADuM3400 Datasheet & AN-793)

    In the link below, there is no problem with 8kV for contact discharge and 15kV for air discharge…

  • ADUM1400 Inputs enable behaviour

    Hi, I have found a strange behaviour in the ADUM1400BRWZ: the datasheet says the pin 7 shouldn't be connected but if I don't connect it the inputs are disabled. Then I tried to connect pin 7 first to GND1 and then change it to VDD1 to see the diferences…

  • ADuM1400 Latch up trigger current

    Hi
    I am considering latchup with the ADuM1400.

    There is a description about latch-up trigger current in AN-793,

    and there is a description to limit the current to 25mA or less that is lower than this value.

    How much is the latch-up trigger current in the…

  • ADUM5400 and ADUM1400 EMI issues

    Hello ADI Support:

    My customer is currently designing an isolated serial card using the ADUM 5400. The PCB dimensions will be the standard PC-104 card size. Along with the ADUM 5400, They will also be using the ADUM1400 to isolate other signal lines…

  • ADuM1400 VDD2 unpowered cause any problem ?

    Hi,

    Our customer made a question about ADuM1400 in their prototype board, which VDD2 is unpowered a little while(maybe around 10ms) during power regulator starting-up to 3.3V triggered by a power switch, against 5V VDD1 is always powered, however there…

  • The distance between ADUM1400 components

    Hallo,

    can you say me are correct placed on the board? The distance between elements is measured 4mm. We will use FR4 material for PCB(1.2mm 4 Layers).

    Thanks

  • ADUM1400隔离没有输出

    供电用的混合3.3,5V供电，供电正常，输入端的信号位5V，频率在2MHZ，带宽在ADUM1400BRZ10M范围内，但是经过ADUM1400隔离之后就没有信号输出（也不是完全没有，大概有0.X的样子，也不是0V），电路图如下所示，求帮忙解答一下，谢谢！
