DE-ACCM3D Datasheet, PDF (2/5 Pages) List of Unclassifed Manufacturers – Buffered ±3g Tri-axis Accelerometer

Measuring acceleration and tilt
The voltage outputs on the DE-ACCM3D correspond to acceleration being experienced in the X, Y and Z
directions. The output is ratiometric, so the output sensitivity (in mV/g) will depend on the supply voltage.
Sensitivity and accuracy
Here are some typical sensitivity values for common operating voltages:
Operating voltage
Sensitivity
3.6V
360 mV/g
3.33V
333 mV/g
(default when using onboard regulator)
3.0V
300 mV/g
2.0V
195 mV/g
Due to manufacturing variances when Analog Devices makes their accelerometer chips, these values aren’t
always set in stone. Sensitivity can vary by up to 10% in extreme cases, and the 0g bias point can vary up to
5% on the X and Y axes, and 10% on the Z axis. For projects that require a very high degree of accuracy, we
recommend that you incorporate measured calibrations into your hardware/software.
