Section Two
Accelerometer Overview:
Motorola’s series of acceleration sensors incorporate a
surface micromachined structure. The force of acceleration
moves the seismic mass, thereby changing the g–cell’s
capacitance. Coupled with the g–cell is a control chip to pro-
vide the accelerometer with signal amplification, signal
conditioning, low pass filter and temperature compensation.
With Zero–g offset, sensitivity and filter roll–off that is factory
set, the device requires only a few external passives. In fact,
this acceleration sensor device offers a calibrated self–test
feature that mechanically displaces the seismic mass with
the application of a digital self–test signal. The g–cell is
hermetically sealed at the die level, creating a particle–free
environment with features such as built in damping and
over–range stops to protect it from mechanical shock.
These acceleration sensors are rugged, highly accurate
and feature X, XY, and Z axis of sensitivity.
Motorola’s acceleration sensors are economical, accurate
and highly reproducible for the ideal sensing solution in auto-
motive, industrial, commercial and consumer applications.
