  12. Be careful...you should only have to use one op-amp for what you are doing.
  13. It sounds like you want the op-amp to amplify your signal as much as
  14. it can, then pass it to another one that does the same thing.  Op-amps
  15. don't work like that...just use a standard non-inverting op-amp configuration
  16. and set your gain...if you set it too high, then the output will just switch
  17. back and forth between the two supply voltage rails --> high amounts of
  18. distortion!
