True. But I think Dave was saying that with a +/- 5v supply, the output
would only be able to get a 5v p-p signal. I would think it would get close
to both the 5 and -5 supply giving close to a 10v p-p output.
Like the original poster mentioned when he observed an approx 8v p-p output.
And back to the original poster, yes if he required an absolute minimum of
10v p-p out, yes his rail supplies would have to be in line with that
requirement.
