Hot-selling and scarce MMA7455LR1 ±2g/±4g/±8g Three Axis Low-g Digital Output Accelerometer LGA14 spot stock
MMA7455LR1 ±2g/±4g/±8g Three Axis Low-g Digital Output Accelerometer LGA14 spot stock
Product Descriptions
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 customer calibrated using assigned 0g registers and g-Select which allows for command selection for 3 acceleration ranges(2g/4g/8g). The MMA7455L includes a Standby Mode that makes it ideal for handheld battery powered electronics.
