The output voltage increases from the Zero Acceleration Output for
positive acceleration and decreases for negative acceleration.
Best Fit Straight Line.
Output is ratio metric with supply voltage in the range of (5.0 ± 0.5) V.
Includes effects over operating temperature range.
1 Hz to 10 kHz.
Applying the self-test input voltage simulates an acceleration. The
sensor output is proportional to the square of the voltage difference
between the self-test input and the positive supply. When not using the
self-test function, the self-test input pin should be connected to the
positive supply voltage. For detailed description refer to Technical Note

Self-test input voltage is with respect to supply voltage. For example, if
supply voltage is 5 VDC then Vst = -5 V is equivalent to ground.
The useful frequency range is defined as the range of frequencies over
which the device sensitivity is within ±5% of the DC value.
The alarm output is a digital output which is 0 V during normal operation
and 5 V when the output voltage of the accelerometer die is outside the
normal range. This is the case if there is a malfunction of the
accelerometer or a broken wire bond to the sensor.
