• ADuM5241

    Truth table in datasheet claims that when Vdd and Viso is unpowered, inputs are
    X, and outputs are Z. I am experiencing that the isolated input and output
    sinks about 130uA in this state, which is causing me some trouble. When the
    device…
  • ADuM5241 alternatives

    Hi all,

    I would need a two channel isolator with just one side supplied ( Iso power, I guess) to isolate an UART.

    I don't require to power anything, just to supply from one side.

    My first idea was to use ADuM5241, because it has ervrything I need in…

  • ADuM5241 overvoltage protection

    In datasheet table 5 it says: "Highest Allowable Overvoltage Transient
    overvoltage, tTR = 10 seconds VTR 4000 V peak" . Does this mean that isolator
    can withstand standard like (IEC61000-4-5 Level 4) 4 kV surge test? What about…
  • ADuM5241/ADuM5242 Power Consumption

    Are there any low power alternatives to the ADuM5241/ADuM5242? The maximum quiescent current is over 100mA!

    My requirement: 2.5kV isolation, 1.8V - 5.5V at 100uA output, lower input current draw, small package, single channel isolated feedback

    I am…

  • EMI problem with ADuM5241

    Posting this for a customer, they are experiencing high 550MHz emissions from an ADuM5541. Do we have any application hints to improve this?

  • ADuM5241:  Application hints for addressing EMC problems in order to pass CE test?

    Are there any application hints for addressing EMC problems in order to pass CE
    test? Are Ferrite chokes recommended for VCC?

     

    ADuM5241 is extremely immune to EMI and can only be affected by extremely large
    currents operated at high…
  • ADuM5241: What output impedance can we expect in Z state when Viso is unpowered?

    Truthtable in datasheet of ADuM524x Rev.A page 9 says that the output is in
    "Z"-State, when Viso State is unpowered. We have a problem, that VOB is
    influencing other functions in our design although pin should be "Z". How is …
  • I need a simple circuit to convert ADum5241 iCoupler isolator I/O to 3.3 volt levels

    I have used the ADum5241 iCoupler before but you need to run it from 5 volts in order to get it to work properly (can't use 3.3 volts).  The IC is nice and small which is great but interfacing it to 3.3 volt logic on the VDD side ends up taking way…

  • ADUM5421通信速率问题

      我现在在产品研发阶段想使用贵公司的ADUM5241这款Isopower芯片,这个芯片的最大传输速率是1Mbps,我准备用这个芯片实现CAN通信隔离。我们的应用中,CAN通信的速率为500kbps,请问贵公司这款芯片能否安全用在我的产品研发中?

          请您给予回复,谢谢!
