• Certificates for the Safety and regulatory approvals for ADuM4190

    Can you provide the certificates for the Safety and regulatory approvals for
    ADuM4190, I can not find them on your website



     

    I have attached here the safety and regulatory approval certificates for
    ADuM4190. These certificates will be posted…

  • difference between the ADuM3190 and the ADuM4190

    What is the difference between the ADuM3190 and the ADuM4190?

     

    The ADuM3190 and ADuM4190 have the exact same function and performance, but the
    ADuM3190 is in the QSOP-16 package for applications where the Isolation voltage
    requirement is 2500V…

  • Why do the ADuM3190 and ADuM4190 have two error amplifier outputs

    Why do the ADuM3190 and ADuM4190 have two error amplifier outputs?

     

    The ADuM3190/ADuM4190 have an EAOUT pin 6 which has an output voltage specified
    to 2.4V and an EAOUT2 pin 7 which is specified to 5.0V. The EAOUT2 pin provides
    a higher voltage…

  • Can I use the ADuM3190/ADuM4190 as an isolated op amp to convert a 4-20mA signal and      how would it work?

    Can I use the ADuM3190/ADuM4190 as an isolated op amp to convert a 4-20mA
    signal and  how would it work?

     

    You could use a 75 ohm input resistor to convert the 4 – 20mA signal to a 0.3V
    to 1.5V signal, which would fit the input common mode…

  • ADUM4190 applicaion issue

    Hi ADIexpert

    I would like to use the refout1 of ADUM4190 as a voltage reference to my other circuits in the schematic

    I connected the REfout1 to the non invert pin of a TL074 to build a voltage follower without attaching any loading on the output of TL074…

  • RE: ADUM4190 design question

    Today, I had the same problem.I read your reply, but I still don't understand.What I want to ask is,how to use ADUM4190 as voltage follower?how to design the circuit?Looking forward to your reply.

  • ADUM4190 Input voltage range

    Hello

    Could you teach me about the input voltage range of ADUM4190 ?

    I can not find the description of input voltage range in the datasheet. 

    I thought that input voltage range of ADUM4190 means input common mode  range (0.35V~1.5V)  desiceibed in the datasheet…

  • 请教关于ADuM4190的使用问题:如何使其作为电压跟随器使用?

    我需要从+IN输出0-5V,使用ADuM4190作为电压跟随器,是的EAOUT获得相同的输出,但是经过实际电路焊接测量,始终得不到作为电压跟随器的输出,因此想请教我的问题出在了那里?  我该怎么做才能实现这样的电压跟随器的输出呢?  谢谢,期待回复
