pedja089:-
I did see your post. Are you suggesting to use that circuit on the output from the DAC? I thought the sine wave was representing an AC supply.

Dave/Henrik:-
I've just done a bit of reading and it looks like "cap coupling", "AC-coupling" and pedja089's schematic are all the same thing. I will give that a go and see what happens.

Henrik:-
I have plenty of board space for once so if I do need to add extra stuff it won't be a problem.
