Technical Data
±2g/±4g/±8g Three Axis Low-g
Digital Output Accelerometer
The MMA7456L 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 customer calibrated using assigned 0g registers
and g-Select which allows for command selection for 3 acceleration ranges
(2g/4g/8g). The MMA7456L includes a Standby Mode that makes it ideal for
handheld battery powered electronics.
