ADuM5000 is good for up to 100mA as the specs page for the Aimagin's dongle suggests. (of the possible 400mA per USB spec, but um, not likely a small sound card will use that.)
Unfortunately, I've been having a problem with my one using it on my MD11.
a) When the dongle is connected, there is periodic crackling and short sample drops that don't occur when using the device without the isolator.
b) The max the dongle can do is 24b/48khz, while normally the same DAC can do 96k/24b and 192k/24b. (pit I don't have a normal isochronous type DAC to check it with, maybe it's something with musiland again)
Plus they ship it without a case, which is a bit disappointing for $69 (bit of a rip-off rip-off, for $10-15 worth of components)...(at least they should make it an option for people who aren't going to put it in their own box. )
> I would figure most of these ADuM4160 based isolator designs are more less the same, save for the difference between those that come with a separate power source and others that are entirely USB powered.
there aren't many parts on them, and it's probably a ref design from AD
?... Aside from that there's the Aimagin one using 5k and 4160, but as I said above, I'm not really a fan right now.
