Hi all,

We all know the problems with QRM on the VLF/LF/MF devices in combination with computers. Sometimes even with good grounding, adding loads of common mode chokes, some QRM remains.
At work i just jumped over that device: ADuM4160

I can very well imagine there are many of you (as well as me) who would benefit at least a bit when using that device.

Worth to play with?

73, Stefan/DK7FC

PS: Maybe be used in combination with an ADuM5000 as shown in this image: http://www.dajac.com/blog/wp-content/uploads/2009/07/adi_usb_isolator_4160_circuit.png if that doesn't add QRM again...
