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.
