• RE: AD7609 - Powering from ADuM5400

    Jonathan,

    Just for clarification. Are you stating that the output of the ADum5400 is clean enough and can be used to power the AD7609? Do you have any information on the peak-to-peak noise generated by the ADum5400?

    Thanks,

    John

  • RE: ADUM5400 EMI reduction

    Falk:

    I agree that if you don't need the extra power provided by a second isoPower output , then you can use an ADuM1410 powered by one ADuM5400 VISO. You need to connect the 5V supply on the primary side to VDD1 of both ADuM5400 and ADuM1410 (just like…

  • ADUM5400 and ADUM1400 EMI issues

    Hello ADI Support:

    My customer is currently designing an isolated serial card using the ADUM 5400. The PCB dimensions will be the standard PC-104 card size. Along with the ADUM 5400, They will also be using the ADUM1400 to isolate other signal lines…

    My part has startup problems during Power Up

     

    This startup issue looks like that described in the attached note as symptom no

    Can I use the ADUM54xx devices in a redundant parallel configuration? I would

  • 使用ADuM5400时遇到的问题

    ADuM5400的电路原理图如图1所示。

    根据原理图连接好电路(原理图中的电容和电阻未安上),5V供电,使用示波器输出的方波信号作为输入信号,使用示波器对ADuM5400的输入和输出信号进行测量,如图2所示。

    .

    示波器测量到的输入和输出信号如图3所示。

    测量到的输入信号不是原始的方波信号,并且输入和输出信号有很大的差别,请问有可能是哪里出了问题?

  • RE: Stability in Viso ADUM5000

    Cris:  The ADuM5000 VISO voltage should not change much over time, but it does change with load and temperature.  See attached 5V data.  You are right the non-inverting amplifier would need a divider on the input or output to reduce the output voltage.  Can…

  • RE: ADUM1301和ADUM5400通电后急剧发烫

    非常感谢您的建议。但我在同一个电源上还连接使用了ADUM1400和ADUM1402,这两个芯片工作正常,没有异常发烫现象,只有ADUM1301和ADUM5400这两个芯片发烫,工作时测量了工作电压也在许可范围内,所以百思不得其解。
