ELECTRO STATIC DISCHARGE (ESD)

WARNING: This device is sensitive to electrostatic

discharge.

Although the accelerometers contain internal 2 kV 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.
