ADXL327
Self test response in g is roughly proportional to the square of
the supply voltage. However, when ratiometricity of sensitivity
is factored in with supply voltage, the self test response in volts
is roughly proportional to the cube of the supply voltage.
For example, at V
is approximately −780 mV for the X axis, +780 mV for the Y axis,
and +1330 mV for the Z axis. At V
is approximately −130 mV for the X axis, +130 mV for the Y axis,
and −220 mV for the Z axis.
The supply current decreases as the supply voltage decreases.
