• RE: ADuM1400 VDD2-GND2 voltages when VDD2 is NOT supplied

    Thank you for your reply.

    I like to confirm one more thing.

    the customer said as follows.

    Is this the same reason and can he fix this problem when he use ADuM140E or ADuM1440?

    He supplied 3.3V between VDD2 and GND2.

    when he measured the voltage between…

  • RE: ADuM764X "glitch filter?"

    I'd add that some digital isolators do not include a glitch filter, such as the ADuM140 series which use OOK signaling. The glitch filter adds directly to the propagation delay, so it may not be utilized in the chip design when the shortest delay is desired…

  • (ADuM140E1)Supply current.

    Hi !

    Q1)

    Our customer want to know the supply current.

    I already asked about this and you gave me ADuM142's spread sheet.

    (ADuM140)Supply current with OOK. 

    Can you give me the same thing for ADuM140?

    Q2)

    Also , ADI's newest iCoupler series…

  • RE: ADuM1411ARWZ & ADUM141E1BRWZ

    Hello Cuttlefish,

    The ADuM1410/11/12 have the CTRL pin, which allows you to select the default output state (High or Low). The ADuM140/41/42 devices do not have this feature - instead you purchase a different part number with default Hi (e.g. ADuM141E1…

  • RE: (ADuM128*)Supply current VS temp.

    Hi Joseph.

    Thank you for your answer.

    I understood that our customers would not be able to decrease the supply current.

    Our customer want to use the iCoupler with 1MBps.

    And also they want to reduce an emission noise.

    So, they want to use 2nd generation…

  • RE: (ADuM14x)How to calculate the supply current when each channel's duty and frequency are not same.

    Kawa-san:

    We looked at your formulas and this is how it should be:

    I don’t think it is right to put negative sign. You should instead use (1 – duty cycle ) to calculate how much the TX will draw current from supply.

     

    The correct formula should be…

  • (ADuM14x)Can ADuM14x QSOP guarantee 3kVrms-1min ?

    Hi 

    I have two questions about ADuM14x insulation.

    Q1)

    ADuM14x had already passed 3kVrms insulation standard.

    Can I say to my customer that ADuM14x(QSOP) can guarantee 3kVrms-1min ?

     

    Q2)

    And at the datasheet page 14, this is written.

    In accordance…

  • (ADuM14x)What will happen if input is HiZ.

    Hi !

    I have some questions about ADuM14x.

    At our customers system sometime the device which is connected to ADuM14x input outputs HiZ.

    So my question are these.
