A quick question regarding OP amp power supplies.
Take for example - my NE5532's.. Datasheet says +/- 22 volts. What I am trying to understand is...
Does this mean max voltage difference BETWEEN the + and - inputs is 22 volts?
-or-
Does this mean I can have a -22 volts AND +22 volts (relative to ground) for a potential (between +/-) of 44 volts?
I have always been confused by this..
