[sdiy] voltage followers

[Thom Ash]

hi everyone!

i was thinking of making a cv buffer for my modular, and i can't find a
schematic to copy on the web, so here come the mundane newbie
questions... ;)

1. will the standard opamp voltage follower configuration [input signal
to + input, output linked to - input] be appropriate here?

2. would it be ok to use one opamp to drive, say, four output jacks, or
should i have one per output?

3. how would i go about implementing an inverted output [like on the
ASys RS230 module]? i was thinking i could use two inverting opamps in
series, with the feedback loop encompassing the whole thing so it still
acts as a follower, and tap the inverted signal from in between the two,
but i can't quite come up with a circuit that i'm confident enough about
to actually build...

thanks!
