Freescale Semiconductor Technical Data ±2g/±4g/±8g Three Axis Low-g Digital Output Accelerometer The MMA7455L is a Digital Output (I2C/SPI), low power, low profile capacitive micromachined accelerometer featuring signal conditioning, a low pass filter, temperature compensation, self-test, configurable to detect 0g through interrupt pins (INT1 or INT2), and pulse detect for quick motion detection.

0g offset and sensitivity are factory set and require no external devices.

The 0g offset can be cust
