What's the best thing to do with unused opamp i/o's in dual/quad opamp
chips (for lowest power consumption)?

** Depends on the op-amp - but in general, to disable the things connect
their " - " input to the output and ground the " + " input, plus leave
the output unconnected.

Some op-amps are not stable down to unity gain and may oscillate in the
above voltage follower mode.
