• ADUM2401 VCC ringing issue

    Hello

       Below is surge testing waveform. CHI is Vcc pin of isolator. CH2 is Surge input to PSU unit. While surge input PSU unit, VCC will happen ringing of VCC of ADUM2401 internally. But the function still work normal.

       if VCC ringing between 1us, has…

  • ADUM2401: Common mode voltage

    I have some questions about the ADuM140x, ADuM240x and other ADuM ICs.

    (A) The ADuM1401 and ADuM2401, for example, have three direct and one reverse
    channels.

    Questions:
    (1) What channels, direct or reverse, may be under high common…

  • ADxL345 and ADuM2401

    Hi,

    In my application I am using ADXL345 Accelerometer.
    The Microprocessor used is C8051F120.

    At beginning of the project I used the ADXL345 directly connected to the micro (without isolation) and the accelerometer work perfectly.

    I have added some…
