I'm trying to find a good and practical current sensor and I found this: Si8519 http://www.silabs.com/Support%20Documents/TechnicalDocs/Si85xx.pdf
My idea is monitor AC Mains current, so this Si8519 works up to 20A.
After read the pdf document I have no idea how to wire this stuff to a Raspberry Pi. I have searched on google, but still no results, does anyone know about this chips?? Not even a single example found on the internet.
I'm using 20pin chip with legs. Also I saw very IIN and IOUT on the chip, don't know how to use it and I don't want to blow up the chip.
Can someone help me understanding how to wire this stuff?
