Thanks for the answer. I use the 13600/13700 almost every time,
and I have used all three methods (discrete, follower, inverter)
in different projects myself - but what I was really looking for
was some theory about the two alternatives I named (in *some*
applications the level shift of a discrete buffer is not that good).
I was really asking about pro's and cons of the two named
alternatives, and to make it easy I named a 3080. I might add that
opamps I use to use the TL07x series.
So given these to components (for what reason ever) - what would
the pro's and con's for either configuration?
