  • ADUM3190

    During startup, output of primary amplifier (eg EAout2) is at high level when VDD2 is lower than 3V.

    How to avoid this behaviour when ADUM3190 is included in a regulation loop.

    Sartup is impossible due to the wrong information sent to PWM controller…

  • ADuM3190

    Hello,

    I'd like to use the ADuM3190 in a DC/DC converter project. For this purpose, I'm trying to build a simple PSpice model of the ADuM3190.

    What I need is some information about the DC transfer characteristic of this device.

    Using my Pspice…

  • RE: ADUM3190-Isolated Error Amplifier

    Devarajan: In response to your questions:

    1.  I checked, we don't have EMI radiated emissions data on the ADuM3190.  I just returned from the emissions lab for another product.  I don't have emissions lab tests scheduled.  Next time we go, I will…

  • 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…
  • What is the Gain Bandwidth product of the ADuM3190/4190?

    What is the Gain Bandwidth product of the ADuM3190/4190?

     

    The Gain Bandwidth product of the ADuM3190/4190 is 10MHz typical per Table 1 of
    the  datasheet.
  • What does the 1% accuracy of the ADuM3190/4190 include?

    What does the 1% accuracy of the ADuM3190/4190 include?

     

    The 1% accuracy specification includes the use of the ADuM3190/4190 in an
    isolated feedback loop and includes drift over temperature from -40˚C to 125˚C.
  • ADuM3190/4190 isolated error amplifier be used as an isolation amplifier?

    Can the ADuM3190/4190 isolated error amplifier be used as an isolation
    amplifier?

     

    The ADuM3190 and ADuM4190 are ideal for linear feedback in isolated power
    supply applications.  Since they have an amplifier input and isolated amplifier…
  • RE: ADuM3190 side 2 power supply

    Irvin: If you use the ADuM3190 as a linear isolator, the input to output gain will vary from 0.9 to 1.1 or +/-10%.  But, if you are isolating a feedback voltage you may want to use the ADuM3190 as an isolated error amplifier and use the 1.225V internal…

  • Mesaure AC Line Current (230V AC)

    Is it possible to use the ADuM3190 to measure current in 230V AC line?

     

    The ADuM3190 was designed for a 0.35V to 1.5V input, while the 230VAC current
    from a resistor would have a positive and negative voltage, and would probably
    be a…
