ADXL326
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
ADXL326 is approximately −107 mV for the X axis, +107 mV
for the Y axis, and +181 mV for the Z axis. At V
test response is approximately −18 mV for the X axis, +18 mV
for the Y axis, and −31 mV for the Z axis.
The supply current decreases as the supply voltage decreases.
