Hello.
I have to make my small signal path (souce delivers 1mV ac) able of withstanding 1kV and therefor need some isolating device. The easiest and cheapest way of dealing with this must be an optocoupler. But since they're not really linear my question is how much they will distort my signal? Especially since the signal is very small. Will I introduce a lot of noise by amplifying the signal before the coupler and damp it afterwards?
Please have a look at my schematic and comment it!
