±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 idea l for handheld battery powered electronics.
