• ADuM3201 solderability

    ADuM3201 was selected by our HW development and I have to check producibility
    for lead free SMD process.
    Missing data about :
    solderability according to J-STD 020 or similar, lead free / RoHS confirmation;
    pin Termination material …
  • Failure Analysis of ADuM3201

    Dear Experts,

    I have used ADuM3201 for basic interface isolation.

    I made a mistake when I was testing the board in the field.

    So that the overvoltage stress had been appeared in second side.

    Then, the ADuM3201 was failure, the pin6 had a special output…

  • ADuM3200/ADuM3201 Insulation Dielectric Strength

    ADuM3200/ADuM3201 Datasheet Rev. F: Table 27 states Minimum Internal Gap (Internal Clearance) of 0.017 mm.  For a device claiming 1 minute withstand tolerance of 2.5 kVac, this would suggest to me a peak dielectric strength for the insulator in the order…

  • MTBF for ADuM3200, ADuM3201, ADR395, ADM485

  • RE: ESD issue

    Hi Joe-san,

    I visited the customer to explain ADuM3201 is better than ADuM7241.

    The customer wants to know how strong ADuM3201 is compared with ADuM7241.

    The customer is confused because ADuM7241 is stronger than ADuM3201 according to the reliabirity…

  • RE: Issue with ADUM1201BR

    Hi Dave,

    Good thought,

    I verified for the driving source by disconnecting the connection between Pin 2 of ADuM1201 and MAX3313 Pin 6.

    ADuM1201 is the driving source!!

    I even verified by connecting pin 7 of ADuM1201 to the respective ground still I…

  • RE: LTM8047EY隔离电源应用

    你好,邮件已回复,5VXK负载就一个MAX3232和一个ADUM3201;5V422负载两个ADUM3201和两个max490;LTSPICE模型已仿真,确实是负载不一样,驱动电流不一样,输出电压始终在5V的%2以下浮动;但是我的实际应用确实有问题;5V422这路正常,5VXK这路不正常必须并联一个200R; 可以的话 回个电话13621110098.谢谢。

  • RE: The refresh pulses of ADuM3211

    Hi Andrew, 

    The ADuM3211 is an edge encoding architecture. The isolator sends either a single or double pulse when the input detects a state transition. If the input does not detect a change within ~1us, it will send a refresh pulse. The refresh is for…
