If So, what are they? I notice that right along side a current sense amp is a diff. amp in catalogs, So whats the difference? If Im just monitoring how much current Im using using a sense resistor, wouldnt a diff amp do just as good?
Ive been having trouble finding a current sense amp that has a Gain of 100 and is available in through hole form that Mouser sells. The reason for using mouser other than digikey is because I need a PIC18F1320 for a project, and I refuse to pay $5 for it at digikey when I can get it for Much Less at mouser.
