100% tested in production
Qualified during product validation
The product is factory calibrated at 2.5 V in room temperature.
Typical values are not guaranteed.

. The measuring range is tested on sensing element level. FS = 2g.
Offset temperature error = {Count(0g)-Offset} / Sensitivity [ g ]. Sensitivity = Calibrated sensitivity.
Offset= Calibrated offset.
Sensitivity = {Count(+1g) - Count(-1g)}/2 [Count/g].
Sensitivity temperature error = {[Count(+1g)-Count(-1g)]/2 - Sensitivity} / Sensitivity x 100% [%].
Sensitivity = Calibrated sensitivity.
From straight line through sensitivity calibration (+1g, -1g) points.
The cross-axis sensitivity determines how much acceleration, perpendicular to the measuring axis,
couples to the output. The total cross-axis sensitivity is the geometric sum of the sensitivities of
the two axes which are perpendicular to the measuring axis. The angular alignment error
between X, Y and Z axis is included into the cross axis sensitivity.
