Xtrinsic MMA8491Q 3-Axis Multifunction Digital Accelerometer
The MMA8491Q is a low voltage, 3-axis low-g accelerometer housed in a 3 mm x 3 mm QFN package. The device can accommodate two accelerometer configurations, acting as either a 45° tilt sensor or a digital output accelerometer with I2C bus. • • As a 45° Tilt Sensor, the MMA8491Q device offers extreme ease of implementation by using a single line output per axis. As a digital output accelerometer, the 14-bit ±8g accelerometer data can be read from the device with a 1 mg/LSB sensitivity.
