Although the accelerometers contain internal 2 kV ESD performance or cause failure of the chip. When handling the protection circuitry, extra precaution must be taken by the accelerometer, proper ESD precautions should be followed user to protect the chip from ESD. A charge of over 2000 volts to avoid exposing the device to discharges which may be can accumulate on the human body or associated test detrimental to its performance. equipment. A charge of this magnitude can alter the MMA3202KEG Sensors 2 Freescale Semiconductor, Inc.
