• 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…

  • 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 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…
  • 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…

  • Why does ADUM6401 power output latch low with power interrupt?

    I'm using an ADUM6401CRWZ in conjunction with an ADUM1201WTRZ for isolation to an AD7714YRU A/D circuit.  From a cold start everything comes up no problem but if the main DC power is cycled off/on, 9 times out of 10, the power output of the 6401 will…

  • ADUM6401是否可以用作STM32F4单片机的SPI接口隔离输出


  • RE: ADUM640x - Input ripple


    I don't see how changing from the ADuM5401 to the ADuM6401 should change the noise on the inputs, since they are basically the same die, but with a thicker polyimide insulation on the ADuM6401.  Are you using the same exact PC board?  Can…

  • RE: ADuM5401 layout question

    Kevin: The ADuM6401 has the RI package available which has expanded creepage of 8.3mm as seen in its table 16, attached.  Can you use the ADuM6401 in RI package?

  • RE: medical ADC isolation


    finally used ADuM6401 (SPI) + EVL board + ADC and connected it to Arduino

    working great

    thanks all
