I have a low power design that I'm trying to get as far down
as possible.  It sits at ~980 uA right now, but over 500 uA of
that is a "low power" op amp that I'm shopping for a
replacement for.

I've already gone through the PIC, minimized its current draw
as much as possible (pins not pulled externally are outputs,
being driven high or low).  The remaining ~440 uA still seems
a bit high, since everything on the board is shutdown but the
voltage regulator.  The sleep currents for the other
components on the board sum up to less than 200 uA.  Can
anyone give me some general troubleshooting advice to find
the hog that's sucking up the other 250 uA?

Mike H.
