• ADuM6401 and common mode transient immunity

    On my measurement board there are some analog inputs that should be galvanic
    insulated from the rest of the board. So I want to use the ADUM6402. A
    requirement for our design is that it can handle a surge pulse (common mode,
    line - earth) with…

  • ADuM6401 Viso无输出


    我们在产品上验证ADuM6401时发现Viso管脚没有5V电压输出(Vsel与Viso连接);尝试采用直接用外部DC 5V电源供电(无限流),Viso仍然没有5V输出。请帮忙分析一下原因,谢谢!

  • ADuM6401 output state at VDD1 off


    Please let me know your adivce for  output state of ADUM6401 at VDD1 off.

    We think  that output becomes high-impedance throguh below 2 pattern  from the datasheet description.

    Is it correct ?

    1:   ADuM6401 holds last logic state

    2:   output becomes…

  • ADUM6401 Different Power and Logic Voltage

    Hi all,

    I'm attempting to use the ADUM6401 to send 5V power over an isolation barrier but 3.3V logic as well. In the datasheet, it states that VDD1 and VDDL need to be connected together. Is it possible to have different logic and power supply voltage…

  • Problem with ADuM6401


    I have a problem with ADuM6401. I use this part for isolation AD7793. I have it on SPI bus with other parts (LCD, EEPROM, another AD7793 (non-isolated), DAC).

    And now about my problem. When ADuM6401 is connected to bus, there is a problem with…

  • ADuM6000 and RCin/RCsel High Level thresholds

    Logic levels on pins RCin / RCsel of ADuM6000 are not described
    in the datasheet.

    What is the minimum High voltage Threshold for these logic pins?


    The RCin/RCsel input is a standard digital input and has the same threshold
    levels on the ADuM6000…
