Absolute maximum ratings
Stresses above those listed as “absolute maximum ratings” may cause permanent damage
to the device. This is a stress rating only and functional operation of the device under these
conditions is not implied. Exposure to maximum rating conditions for extended periods may
affect device reliability.
Note:
Supply voltage on any pin should never exceed 6.0V

Terminology
2.5.1
Sensitivity
Sensitivity describes the gain of the sensor and can be determined e.g. by applying 1g
acceleration to it. As the sensor can measure DC accelerations this can be done easily by
pointing the axis of interest towards the center of the Earth, noting the output value, rotating
the sensor by 180 degrees (point to the sky) and noting the output value again. By doing so,
±1g acceleration is applied to the sensor. Subtracting the larger output value from the
smaller one and dividing the result by 2 leads to the actual sensitivity of the sensor. This
value changes very little over temperature and also very little over time. The Sensitivity
Tolerance describes the range of Sensitivities of a large population of sensor.
