Hi Denny,
I hope you can answer a few questions so we can get to the root of the problem. What input voltage are you applying to circuit and what exactly are you getting at your output? Are you not getting enough gain or is the output railing to the supply? Also, if you don't mind, could you provide the resistor values that you used?
I would also like to confirm whether you are referring to figure 30 in the datasheet... that shows the internal schematic of the part. I thought you might be referring instead to figure 31.
Thanks!
Kris
