• Isolated voltage ADuM5028-3BRIZ :: ADC converter

    Hello,

    I'm searching for a solution which could provide isolated 3V3 voltage to supply the ADC converter. It looks that ADuM5028-3BRIZ would be a very good choice, but I'm not completly sure if it will be the best choice for my application, because of…

  • ADuM5028 Output Capacitance

    Hi there,

    I'm working on an inverter design that measures phase currents using ADuM7701 ADCs, which require floating power supplies. To keep things simple, I'm considering exclusively using a DC/DC such as the ADuM5028 instead combining a DC/DC…

  • ADuM5028

    Hello,

    I am trying to use ADuM5028 to supply gate driver with isolated 5V, but  I have read in the datasheet in page 11 that "It is recommended that the ADuM5020-3BRWZ and the
    .
    ADuM5028-3BRIZ are only used for 3.3 V input to 3.3 V operation, therefore…

  • ADUM5020 and ADUM5028 for RS-485 Circuit

    Hello,

    I would like to use ADUM5020/ADUM5028 for a RS-485 circuit. With ADM2795E transceiever.
    120Ohm Termination, 3.3V bus and 500kbit/s. 

    Do you have an application note or example design about power calculations?
    Thanks for any help.

  • ADuM5028 and ADuM240D0 4 layer board layout?

    Hey,

    I am using the ADuM5028 to power two ADuM240D0 isolators, and I am using a 4 layer board. So far I have followed the advice from from the two layer EVAL-ADuM5028EBZ evaluation board, adding the two ferrites. I was wondering what to do with the inner…

  • RE: Replacement ADUM6421

    Hi Cedric, 

    There is not another device pin-compatible with the ADUM6421ABRNZ5. Some layout changes would be needed. 

    The most similar functionality for the isolated dc/dc converter would be the ADuM5020/ADuM5028/ADuM6020/ADuM6028.

    The digital isolation…

  • RE: ADM2587E TVS surge protection

    Hello, 

    The protection schemes from the CN-0313 circuit note below can be adopted for use with the ADM2587E

  • RE: Is there an isolated DC/DC 3.3V efficient at low current (less than 2mA)

    ADuM5028 is a very compact solution and although efficiency with small load is low, alternatives might be the same or lower. There are discrete power supply options such as flyback converters (e.g. LT8302) that offer higher output power & voltages, 

  • RE: ADuM5020/5028 Design Guild

    Both ADUM5020 and ADUM5028 should be released already.

    You can find SCH and LYT examples on user guides of Eval Boards.

  • RE: ade9153a

    Hi Belaj, 

    The quick answer is yes. The ADuM5000 can provide 60mA @ 3.3V isolated power. There are some other part and package options available depending on your application needs. So to say it with package and HV rating options, the ADuM5000/ADuM6000 can…
