  • disable adum1310 completely

    Hi,

    first my application is a galvanic isolated DAC with 4..20mA Ootput. I am using the adum1310 for the galvanic isolation of the Serial Interface of the loop powered AD421. I am using up to 6 of these couples parallel to transform digital data into…

  • Comment on IEC 61508 A Deep Dive

    Hi Leonfun, I am not sure I understand your comment but I will reply as best I can. First identify the hazards. If the hazard can then somehow be addressed using a circuit that looks something like a sensor+logic+actuator then you are talking about functional…

  • AD421电路及场效应管问题

    附件是我的电路图，请问电路图是否有问题，另隔离我用的磁耦ADUM1310，场效应管我用的DN2540，买来DS用万用表测量是通的，放电后DS脚阻值5百多，按理应该是好的？但是我的结果不多，240欧姆的电阻早上是10V，刚刚又没有了，而且AD421开始发热，有点烫，我的问题主要是1.电路图是否有问题 2.场效应管是否是好的？如果有做过的是否可以上传原理图给我参考？谢谢谢谢！

  • TVS ground problem

    Hi,

    I must protect my device. To do it i have used isolated DC/DC power source, and two ADuM1310. Problems occur when i should connect TVS to ground . I dont know which place is better, or im  not sure in 100%. Isolated ground or field ground. I think…

    How to Build a Functionally Safe Motor Control Circuit

    IEC 61800-5-2 is an industrial standard which covers the functional safety of variable speed drives. In effect it tells you how to build a safe motor control circuit. In this blog I will discuss an example circuit found in Annex B of IEC 61800-5-2 to…

  • RE: ad421异常问题

    若采用两线制24V电流环，就不能使用光耦，光耦消耗电流太大，在AD421的datasheet上采用ADuM1310隔离。

  • RE: AD7793 output clamped to all zeros

    Hi Jelelnie 

    Thanks for your reply. 


    Unfortunately, I can't show you circuit diagrams as they will reveal sensitive company information, and I haven't got authority to do that. 
    What I can tell you is, that through a header with SPI signals and…

  • Digital Isolation Overview for AC Voltage Motor Drives

    This technical brief compares methods of isolation in a traditional motor controller design. The Boston Engineering brief details the benefits of digital isolators compared to traditional optocouplers — which include reduction in cost, component count…
