Hi all I bought some of these ACS712 current measuring modules in assorted current ranges (5A and 30A I think).
The datasheet says that the sensitivity of the 5A configuration is 185mV/A. This is counter intuitive as you would expect that the sensitivity would be 2.5/5 V/A; to fill the whole voltage range.
Can someone please explain to me why the chip uses that sensitivity? Thanks!
