thanks greenman...did some reading on operational amplifiers.
Drew up this diagram below to show what i belive is how an OP-AMP would be used in my scenario.
Sorry for all the confusion on this guys, new to alot of this.
I appreciate all the help :-D
V+ and V- would be directly connected to the shunts 50 or 100mv output.
Vs+ to the positive side of the power supply
Vs- to the negative side of the power supply
Ground to ground
and Vout to one of the analog inputs into the fusion brain.
As far as obtaining an OP-AMP radioshack shows they sell two models
a TL082/TL082CP Wide Dual JFET Input Op Amp (8-Pin DIP)

and a LM741CN Operational Amplifier (8-Pin Dip)

would either of these work for the application i am using them in? I am not sure how to get one that will work on either regulated or unregulated 12v (for the power supply) and how to figure if it gives me the right ouput (0-5v) for the fusion brain.
