MMA1260D
Freescale Semiconductor
Technical Data
Low G
Micromachined Accelerometer
The MMA series of silicon capacitive, micromachined accelerometers
features signal conditioning, a 2--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 Freescale Semiconductor accelerometers
contain internal 2kV ESD protection circuitry, extra precau-
tion 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 magni-
tude 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 dis-
charges which may be detrimental to its performance.
