ADuM3480 and ADuM3481


I would like to use this device to isolate a pc from other 12 vdc electronics on a marine vessel. Currently I have an FTDi wire ended USB cable interfacing from the pc to the marine nmea network with no isolation. My question is: since the FTDi USB cable needs a driver installed to be recognised, what will happen if on of these devices in the title is installed between the PC and the FTDi USB cable?

Thanks for any help

    Hi Burton:

    it would be better if you could share us more details about this application. now the consideration i could give to you is:

    1. ADuM3480/1 is VDD range is 3.0-5.5V. you need add a regulator between 12Vdc and isolator;

    2. During the period for VDD1/2 to be established, output is default high or low which is depended on CTRL1/2's voltage level. and output will follow input after 1.7uS delay time when VDDx is ready. the communication should avoid this 1.7uS.

    3. the max data rate for ADuM348x is 25Mbps.
