• ADuM5211 and ADuM6211

    Just need a quick answer::. Is the ADuM6211 a drop-in replacement for an designed-for-ADuM5211 PCB? I am not asking the other way round as I know the 6211 device supports  higher isolation voltage than the 5211 device..



  • RE: ADUM5211 ESD immunity

    Eden: In qualification tests for release of the ADuM5211 the ESD testing was done with HBM to ESD test spec ESDA/JEDEC JS-001-2011 network (1.5kohm 100pF) to +/-4000V without a failure.

    Your plan to test to ± 8 kV contact discharge, ± 15 kV air discharge…

  • RE: ADuM5241 alternatives


    You can look at the ADuM5211 which comes in the SSOP package which is smaller than the ADuM5201 and consumes less current than the ADuM5241. 

    Regards, Brian

  • RE: Are there known ADuM5211 start up issues?


    The ADuM5211 schematic seems to have missing pins for: VDD1, GND1 and VDD2, GNDiso pin 19, 15  as well as VIA, VOA, VIB, VOB.

  • Input / Output Voltages ADUM5211 (or 6211)

    Can these devices be used with the "input" voltage at 3.3V, with the "output" (isolated side) voltage at 5.0V ?

  • ADum5211 Isolator Input Current Question

    I am trying to determine much current the ADuM5211 will draw if it is operating at 1Mbps and also powering an isolated LED at 12mA.  Therefore, the isolator power section is supplying about 18mA of isolated current (Idd1=2.7mA and Idd2=2.9mA max at 1Mbps…

  • RE: I need a simple circuit to convert ADum5241 iCoupler isolator I/O to 3.3 volt levels

    John:  We have a newer isoPower digital isolator that can run from 3.3V VDD on side 1 and 3.3V on the isolated side.  It is called the ADuM5211 and comes in the 20 lead SSOP package, which is smaller than the other isoPower devices that come in the 16 pin…

  • ESD protection for equipment that use isopower devices

    We are using ADum5211 / 5401 isolation devices on our product. Will a safety capacitor provided between the two side's ground help in enhancing ESD protection? Presently it is not possible to filter out the ESD from the isolated side to body earth due…

  • Value of Clearance and creepage


    Our customer will use ADuM6402.

    Could you give me your advice what do below difference of value of clearance and creepage  mean ?

    VDE document downloaded on your web site says below.

    Clearance: Over 8.5mm

    Creepage: Over 8.5mm

    (Please refer…

  • iCoupler VDE document


    Our customer will use ADuM6402.

    So he requests VDE document.

    We check the document of VDE 0884 on your web site .

    Its document P.1 says "valid until 2014 12 31"

    (I reffer attachment).
