• ADuM4150: Inconsistency in the clock and SDI outputs

    Hi,

    I'm using ADuM4150  device for SPI communication on my multi-board unit.

    The power supply are both 3.3V supplies. The SPI is running at 10MHz.

    I'm observing a issue as some times the Isolator is providing proper clock output and some cycles of…

  • RE: ADE9000 compliant with IEC 61010-1

    Hi John, The ADE9000 has no isolation so it does not meet 61010-1. Isolation would be needed like the an ADUM241E or the ADuM4150. Use the ade9000 eval board for reference.

  • RE: ADUM3150BRSZ

    Hello Mr. Hansmann

    The ADuM3150BRZ is unique and there is not a pin for pin replacement.  The functionality can be replaced with multiple other chips, and there is the ADuM4150 which is the same functionality in a larger package with higher isolation ratings…

  • RE: ADUM4150BRIZ: Isolation of the VDD

    Hi Nanjunda, 

    Its certainly possible to run both sides of the device from the same power supply. The VDD1 and VDD2 supply pins of the ADuM4150 are independent. The primary and secondary sides of the isolator are actually completely separate die. 

    But just…

  • to know the current ratings of side 1 and side2 for ADuM4150BRIZ spi isolator ?

    Dear Sir,

       I want to know the input and output current ratings and power ratings of  ADuM4150BRIZ spi isolator IC for both sides ?? 

    I am using 3.3v supply on both sides.

    Can you tell me in primary side and secondary side versa ?

    Thanks in Advance

  • RE: EVAL-ADUM3150z board

    Hi Torino,

    You can use an ADuM3150 to evaluate an ADuM4150. Refer to the EVAL-ADuM3150Z User Guide Geneneral Description section. Just to summarize it, the devices differ by high voltage capabilities. Plus the eval boards have no guards to keep a user…
