Buffers in Parallel

D from BC · 2009-11-09T22:29:55+00:00

I've done a virtual ground using an op amp as a buffer.This is for a single supply audio filter.So happens, I have a spare op amp from quad. chip.Should I make the spare op amp a buffer too and put it in parallelwith the other buffer in hopes that the combination will result a'super' buffer with a 50% reduction in output Z?Or.. are the buffers going to fight each other?

I tried 'buffers in parallel' as keyswords, looked around a bit and gave up :(

Someday I'll make the same circuit done with quads (say soic 14) and alternatively with singles (say sot23-6) to see if the layout is easier or more compact.
