Thanks for that, I will give it a go. I read up on op-amps for the last 2 hours, and they are actually very easy to use....don't know why I always avoided them...
Just one thing, my sensor will output 0-5V, so should I not keep a V divider to bring the max sensor output down to 2.5V, and run that 0-2.5 signal through the op-amp at unity gain? Should I buffer the 2.5V ref as well?
Please see the att jpg, does that look more or less right? Are the caps in the circuit required for the 7660 (like the caps with a 7805)?
