SEMICONDUCTOR TECHNICAL DATA
Order Number: MMA1220D
Rev. 1, 06/2004
Low G
Micromachined Accelerometer
The MMA series of silicon capacitive, micromachined accelerometers features
signal conditioning, a 4-pole low pass filter and temperature compensation. Zero-g
offset full scale span and filter cut-off are factory set and require no external devices.
A full system self-test capability verifies system functionality.

ELECTRO STATIC DISCHARGE (ESD)
WARNING: This device is sensitive to electrostatic
discharge.
Although the Motorola accelerometers contain internal 2kV
ESD protection circuitry, extra precaution must be taken by the
user to protect the chip from ESD. A charge of over 2000 volts
can accumulate on the human body or associated test
equipment. A charge of this magnitude can alter the
performance or cause failure of the chip. When handling the
accelerometer, proper ESD precautions should be followed to
avoid exposing the device to discharges which may be
detrimental to its performance.
