• ADuM1301 Output current capability

    I am using ADUM1301; could you please provide me the output current capability
    (sourcing the current) for the pins 13(VOB) and 14(VOA).


    Page 4 of the ADuM1301 datasheet states that the test current is 4mA.
    Furthermore, the output impedance of…

  • ADuM1301: Default output state on power up

    What condition will be at the output of isolator ADUM1301BRW after we apply a
    power if the level of a signal at the input is constant?


    The output state on power up depends on the state of the inputs, enable and
    VDDI, VDDO. The default state is…

  • AD7688: Using with ADuM1301

    We are planing to use either AD7688 or the AD7686 A2D-Converter due to their
    excellent SNR in our application. These converters are capable of a throughput
    of 500kSamp/sec, we want to use this full speed. Thus the aquisition time to
    get out the…

  • Difference between ADUM1301 and ADUM1311 - Pinout same?


    I believe the main differences  are speed and, resulted from that, power. 
    ADUM1301 is up to 90Mbps, whereas ADUM1311 is up to 10Mbps.

    Are there any other significant differences?
    The pin out is the same so far seen.

    That means new parts like ADUM131E1…

  • ADUM1301和ADUM5400通电后急剧发烫

    这是电路原理图,但我只接入两个芯片左侧的5V VCC,其他信号和电源都未连接的情况下,两个芯片在两面针内就急剧发烫!!我查看了手册,并检测了电路,测量了电压,都未发现异常,请问是什么原因导致发生这样的问题?难道是芯片损坏了吗?

  • [digital isolator datasheet description] ADuM1301, etc,,,


    Let me confirm about data sheet description for ADuM1301 or related devices.

    For example, ADuM1301

    On page 21, Figure 13,

    Input voltage and output voltage are specified with VDDI and VDDO.

    But each parameter include both side pins (ex VIA 

  • The reinforced isolation of CAT-2 300V EN61010-1 3rd for ADuM1301/1401BRWZ

    Dear Sir/Madam, maybe Dave C.



    Do you have the evidence document of the reinforced isolation of CAT-2 300V EN61010-1 3rd?

    Otherwise can you recommend another i-coupler fit for the reinforced isolation of CAT-2 300V EN61010-1 3rd?
