• RE: CN0349 RF interference?

    Hi Jgirgis,

    All isolated supplies will have some level of interference, but the ADUM5020 mentioned above would be a good step in the right direction. There is quite a bit of reference material on the product landing page:


  • (ADuM5020)How did reduce ADuM5020 radiation noise?

    Hi !

    This is just my interest but please let us know.

    How did ADuM5020 reduce EMC?

    Does this device use same architecture inductor as ADuM141?

    Best regards

    Both ADUM5020 and ADUM5028 should be released already.

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

  • ADUM5020 and ADUM5028 for RS-485 Circuit


    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.

  • RE: More drive for RS485 Application

    Hi Paul,

    Any idea on what the combined load of the 20 - 50 VFDs is? The ADM2587E can drive a network with a total of 32 unit loads (12kohm) present. If you require to add additional power in order to drive this network, I would expect the network to have…

  • RE: ADUM5000ARWZ EMI issue


    In the past I have heard of applications using a metal shielded enclosure but not specifically using a ferrite sheet.  The new ADuM5020 can be used and does not need shielding or stitching capacitance to achieve CISPR22 Class B emissions.

    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…

  • RE: ADM2587E Protect Function and Safety

    Hi Snow,

    The ADM2587E only has 15 kV HBM ESD protection on the Bus pins. It does not have IEC61000-4 levels of transient protection. In order to achieve some of the specs above it would require the use of external protection components. Please see https…

  • 隔离芯片ADUM5020损坏好多

    设计开发系统必须使用隔离模块,选用了ADUM5020,负载电路为5V/50mA,测试过程中多个芯片损坏,经过分析后,大概得出结论是该芯片空载或过载后出现异常且不可恢复。但是该芯片数据手册上没有明确这一点,且先关评估板资料也未给出说明。哪位ADI工程师能帮助解答下,损坏原因是否为上述原因,或者其他可能原因 。请指正!

    Vbus2 is a 5V power input. 

    If you want to create a bus powered application, you will have to supply an additional isolated DC/DC converter.  We have chip scale converters that will work in a limited way, such as the ADuM5000 and soon the…
