Technical Data
±2.5g - 10g Two Axis Low-g
Micromachined Accelerometer
The MMA6281QT low cost capacitive micromachined accelerometer features
signal conditioning, a 1-pole low pass filter, temperature compensation and g-
Select which allows for the selection among 4 sensitivities. Zero-g offset full scale
span and filter cut-off are factory set and require no external devices. Includes a
Sleep Mode that makes it ideal for handheld battery powered electronics.

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.
