Technical Data
±2.5g - 10g Two Axis Low-g
Micromachined Accelerometer
The MMA6271QT 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.
