The MMA8491QR1 is a Xtrinsic three axis multifunction digital accelerometer in 12 pin QFN package. This low voltage, low-g accelerometer can accommodate two accelerometer configurations. It can act as either 45° tilt sensor or digital output accelerometer with I2C bus. As a 45° tilt sensor, the MMA8491Q device offers extreme ease of implementation by using single line output per axis. As a digital output accelerometer, the 14bit ±8g accelerometer data can be read from device with 1mg/LSB sensitivity. The extreme low power capabilities of MMA8491Q will reduce low data rate current consumption to less than 400nA per Hz.
Ultra fast data output time of 700μs
Supply voltage range from 1.95V to 3.6V
±8g full scale range measurement range
14bit digital output and 1mg/LSB sensitivity
Output data rate (ODR) implementation from less than 1Hz to 800Hz
