I think the package is too dissimilar to extract useful information
from it.  They chose a very interesting method for conveying the
information, too.

Phase-out isn't important; one-off and all that.

Plus, the +/-5g range is a little more than I need.  Since this is
going to be used to measure tremors caused by pharmaceuticals,
the actual acceleration range is pretty small- well within the range
of the ADXL311.

Since this thing is being mounted dead-bug (if you can say that,
for a chip with no "legs"), smaller is only better to a point.
This will be dead-bugged to a substrate (piece of Delrin), which
the wires will lead away from to connect to the amp/signal
conditioning box, which then feeds into the rest of the data
acquisition system.
