Although the Freescale accelerometers contain internal performance or cause failure of the chip. When handling the 2 kV ESD protection circuitry, extra precaution must be taken accelerometer, proper ESD precautions should be followed by the user to protect the chip from ESD. A charge of over to avoid exposing the device to discharges which may be 2000 volts can accumulate on the human body or associated detrimental to its performance. test equipment. A charge of this magnitude can alter the MMA1250KEG Sensors 2 Freescale Semiconductor
