The MMA745xL series 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 zero-g through interrupt pins (INT1 or INT2) and pulse detect for quick motion detection. Zero-g offset and sensitivity are factory set and require no external devices. The zero-g offset can be customer calibrated using assigned zero-g registers and g-select which allows for command selection for three acceleration ranges (2g/4g/8g). The MMA745xL series includes a standby mode that makes it ideal for handheld battery-powered electronics.
