CrossRoads:
Check out page 7 of the datasheet

Get some op-amps from www.dipmicro.com and duplicate the input buffer functionality, feeding the arduino analog pin.
man, you have to be the highest ratio of knowledge:helpful on this board.
I might need some help selecting the op amps, the first one (A1) is a special low noise amp (probably one of the maxim-ic products)
It would be great if they would tell us which of thier opamps they use on the 6675 chip...then I could just buy those!
