±1.5 g - 6 g Dual Axis Low-g

Micromachined Accelerometer

The MMA6270QT 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 four 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.
