ELECTRO STATIC DISCHARGE (ESD)

WARNING: This device is sensitive to electrostatic

discharge.

Although the Freescale accelerometer contains internal

2000 V 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.
