Supply decoupling of split (+/-) supplied op amps?

[treez]

For an op amp supplied with a split supply, do we need to decouple supply with 2 caps?...one from plus to gnd, and also one from minus to ground?

-or will one cap do, -from plus to minus?

Hello treez,

one from plus to gnd, and also one from minus to ground?

Yes, that's the right way.
