• Adum3472

    I have interest in use Adum3472 to isolate two micro controlers and DSS and VGA.

    The problem is: in side A I have a Li-On cell (3V to 4.2V) and in side B I need +5V and -5V and based in DataSheet Adum34x function only in range of 3 to 3.6V or 4 to 5V…

  • adum3472源边供电的问题

    请问ADI的专家, adum3472的vdd1按手册例图是接vcc和vddr,但管脚说明是接NC,vdd1和vddr 在芯片内部是什么链接逻辑 ,如果源边接MCU,为3.3V供电,VCC源需要是5V,这时候vddr用连接吗?是按手册中NC,还是接5V

  • ADI英文论坛问答帖精选- 基本电源为3.3V。对于隔离的测量系统,逻辑器件需要5V电压,电源需要7V电压。ADuM3472可以实现这一点吗?

    ADI专家,您好

    基本电源为3.3V。对于隔离的测量系统逻辑器件需要5V电压电源需要7V电压。ADuM3472可以实现这一点吗?数据手册中指定了5V-5V3.3V-3.3V5V-3.3V5V-15V模式 3.3V-5V模式在理论上可能吗?

     

    如能回复非常感谢。

    谨上

  • iCoupler VDE document

    Hello

    Our customer will use ADuM6402.

    So he requests VDE document.

    We check the document of VDE 0884 on your web site .

    Its document P.1 says "valid until 2014 12 31"

    (I reffer attachment).

  • RE: ADuM 3472 with primary 3.3V, secundary Vdd at 5V and Viso at 7V

    Dani: The ADuM3472 can be used for 3.3V to 5V and will have a stable output voltage.  It can be used to also have a 7V output, if the right transformer and circuit were chosen. For the single output figure 38 of the datasheet, transformer turns ratio …
