I've discovered that my shunts behave unacceptably inductive. I am aware that shunts exist that do not but they are rare, expensive and in the end I feel an indirect measurement might be better all around.
I've looked at some chip like hall sensors, datasheets said the bandwith is 120kHz plus minus.
Why do you suggest I use a core at all? I was thinking if I would have the AC only I might just go with a coil around my conductor, slap an OP on there and see what I get. Cant I get the same a core would give me with just N turns in a coil. It should give a 1:N transformer. Without any saturation issues. But for the time it takes to whip it up and get it to read accurately I might aswell buy some integrated shit. Shit like picrel.
