Again I need a solution that is physically isolated from the source path. This is why I was looking at the current transformers.

The Allegro chips provide electrical isolation of several kV. I'm not sure what you mean by physically isolated.Originally Posted by docwisdom

Yes, they are isolated.
I have used both current transformers and Allegro devices, and I only use the Allegro parts now because of their size, accuracy and ease of use. Even though I mostly use the larger devices, I have used their smaller parts (SOIC-8 package) to measure currents below 100mA.

from what I can see the circuit to be sensed needs to be cut and routed through Ip- and Ip+on the allegro devices.
I need something that does not disturb the circuit to be sensed.

That is true. Looks like you want a clamp-on current probe. I can't help you there. Sorry!
