By the mistake of a shop, i got a bunch of TS921(single) opamps instead of TS912s(dual).
I need a rail-to-rail opamp for an LFO so i will buy one, but meanwhile someone could tell me what opamps should i pop in the socket for testing from the following chips to get close to rail-to-rail operation.

-4558
-TL072
-NE5532
-(one or two Burr Browns, but i rather not mess with them :icon_biggrin:)

supply is +9V, i'd like to get close to a 0V to 9V swing from the LFO

This is all datasheet kind of info. None of them are very close to rail to rail either on input or output.

I think you're down to pot luck. Put in a socket and try.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.
