A slightly unusual Rogowski sensor

[arivel]

I'd like to try this sensor with a bridge amplifier but the problem is finding a good design done right.
I had thought of an opa1632 that drives two power amps in parallel but the electronics experts have sent me papal excommunication stating that it doesn't work 🙂. Maybe Nelson has some nice plans.

There are lots of good designs on the forum: simply pick the one that suits you best
