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.
2.4
Terminology
Sensitivity describes the gain of the sensor and can be determined 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, note the output value, rotate the
sensor by 180 degrees (point to the sky) and note the output value again thus applying ±1g
acceleration to the sensor. Subtracting the larger output value from the smaller one and
dividing the result by 2 will give the actual sensitivity of the sensor. This value changes very
little over temperature (see sensitivity change vs. temperature) and also very little over time.
The Sensitivity Tolerance describes the range of Sensitivities of a large population of
sensors.
Zero-g level describes the actual output signal if there is no acceleration present. A sensor
in a steady state on a horizontal surface will measure 0g in X axis and 0g in Y axis whereas
the Z axis will measure +1g. The output is ideally for a 3.3V powered sensor Vdd/2 =
1650mV. A deviation from ideal 0-g level (1650mV in this case) is called Zero-g offset. Offset
of precise MEMS sensors is to some extend a result of stress to the sensor and therefore
the offset can slightly change after mounting the sensor onto a printed circuit board or
exposing it to extensive mechanical stress. Offset changes little over temperature - see
“Zero-g level change vs. temperature” - the Zero-g level of an individual sensor is very stable
