So you just stick the large straight leads on the IC into any old ferrite core suppressor that fits around the ac wire I am sensing? Is there a specific ferrite core I should be using? Does the plastic coating on the ac line affect the results on these sensors? Or does this actually wire inline in the AC circuit being sensed? I thought these type of sensors were non contact. Then run the output of the sensor through a rectifier to ensure a stable dc current, then to a smoothing capacitor, and finally to the ADC converter on the PIC for measurement. So a PIC can actually read the full output voltage of this sensor? I am not familiar with the voltage/current handling capabilities of most pic ADC's. Can a pic handle the full output of this IC?
