 I also noticed that the 2 axis version is based on a different sensor, from
a different company - not Analog Devices.  I would rather stay with the
tried and true (and temperature compensated).

Be careful - depending on what you want to use it for, the dual-axis version
does not have an on-die temperature sensor like the Analog single-axis chips
do, so it is much harder to properly temperature compensate them.

For a balancing robot, that would be fine - if you're trying to build an IMU
for continuous pose estimation, you might have more trouble.

Later,
