ADG seem interesting for my application but I wonder regarding the 60 Ohms resistance while at ON state...is it really 60 ohm series resistance while it is on? Does it fits to fast communication lines?
Yes, the ADG467 does have a 60 ohm series resistance when it is in an ON state. If you are interested in a channel protector with less ON resistance, then you may be interested in the ADG5462F. It is an quad channel protector with a typical Ron of approximately10ohms.
Here is a link to the production page.
