• ADUM6421A for High Voltage reinforced DC Isolation acc. 60664-1 or 61010

    Hello I will check if we can use the device ADUM6421A for our application.

    Important for me is the maximum ability to be used in.

    We will use use device in DC Systems (SELV to HV-DC) and need reinforced insulation.

    In the Datasheet we can found the foillowing…

  • ADuM6421A Regarding UL's Double Protection

     I see datasheet of ADuM6421A

       But, it is not  UL's Double Protection Specifications .

       Do you have any plans to acquire it?

  • ADuM6421ABRNZ3 with 5V VDDP

    In the ordering guide from the datasheet for the ADuM6421A it states that the ADuM6421ABRNZ3 has a typical VDDP of 3.3V.  Is there any problem with connecting a 5V supply to this part instead?  Or should only the ADuM6421ABRNZ5 be used in that case?

  • AD5270 Daisy Chain Limit and Isolation

    Is there a limit to how many AD5270 devices can be linked in a daisy chain?

    Also, is it possible to daisy chain them through digital isolators, like Analog's ADUM6421A?

  • RE: ADuM6403CRWZ- 10Mhz spi problem

    Hi Sahar, 

    AN-1478 goes into specific application details for isolated SPI. It shows some possible solutions as well. 

    The problem you are having is due to the propagation delay of the isolator and the nature of SPI. In SPI the signals only have a half clock…

  • RE: ADUM 6421A DC - DC Converter power-up issues, Does not output power on the isolated side.

    Dave Z: The ADuM6421A is not releasing until mid December.  To order an eval board now you would need to contact your Analog Devices Sales representative or distributor.

    Regards, Brian

  • RE: Isolated interface chip with power supply

    Hi lijie,

    The ADM3055E and ADM3057E are isolated signal and power CAN FD transceivers. They are in SOIC packages.

    SPI signal and power isolation could be the ADuM5411 in SSOP, ADuM5401 or ADuM6421A in SOIC, if BGA solutions are not possible for this application…
