3 Guaranteed by wafer level test and measurement of initial offset and sensitivity

4 Zero-g level and sensitivity are essentially ratiometric to supply voltage

5 Guaranteed by design

6 Contribution to the measuring output of the inclination/acceleration along any perpendicular

axis

7 Self test “output voltage change” is defined as Vout
