The MMA7360L is a low power, low profile capacitive micromachined accelerometer featuring signal conditioning, a 1-pole low pass filter, temperature compensation, self test, 0g-detect which detects linear freefall, and g-Select which allows for the selection between two sensitivities.

Zero-g offset and sensitivity are factory set and require no external devices. The MMA7360L includes a Sleep Mode that makes it ideal for handheld battery powered electronics.
