Freescale Semiconductor

ELECTRO STATIC DISCHARGE (ESD)

WARNING: This device is sensitive to electrostatic

discharge.

Although the Freescale 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.
