MMA8491QR1

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.
