Technical Data
±4g, ±12g Three Axis Low-g
Micromachined Accelerometer
The MMA7331L is a low power, low profile capacitive micromachined
accelerometer featuring signal conditioning, a 1-pole low pass filter,
temperature compensation, self test, and g-Select which allows for the
selection between 2 sensitivities. Zero-g offset and sensitivity are factory set
and require no external devices. The MMA7331L includes a Sleep Mode that
makes it ideal for handheld battery powered electronics.
