MMA8491Q

Freescale Semiconductor Data Sheet: Technical Data Document Number: MMA8491Q Rev 2.0, 11/2012 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. MMA8491Q Bottom View The extreme low power capabilities of the MMA8491Q will reduce the low data rate current consumption to less than 400 nA per Hz. Features Extreme low power, 400 nA per Hz Ultra-fast data output time, ~700 μs 1.95V to 3.6V VDD supply range 3 mm x 3 mm, 0.65 mm pitch with visual solder joint inspection ±8g full-scale range 14-bit digital output, 1 mg/LSB sensitivity Output Data Rate (ODR), implementation based from < 1 Hz to 800 Hz I2C digital interface 3-axis, 45° tilt outputs Smart grid: tamper detect Anti-theft White goods tilt Remote controls www.DataSheet.net/ 12-Lead Industrial QFN 3 mm x 3 mm x 1.05 mm 0.65 mm Pitch Pin Connections NC 12 Byp VDD SDA EN 1 2 3 4 5 6 NC 11 10 9 8 7 Xout Yout Zout Gnd Typical Applications Related Documentation The MMA8491Q device features and operations ...
