±4g, ±9g Three Axis Low-g

Micromachined Accelerometer

The MMA7331LC 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 MMA7331LC includes a Sleep Mode in

which the device consumes extremely low current. This makes it ideal for

handheld battery powered electronics.
