MMA8491Q Datasheet | NXP Semiconductors

3-Axis Multifunction Digital Accelerometer Rev. 2.1 - 26 April 2016 Data sheet: Technical data PANY PUBLIC 1 General description The MMA8491Q is a low voltage, 3-axis low-g accelerometer housed in a 3 mm x 3 mm QFN package. The device can acmodate 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 ±8 g accelerometer data can be read from the device with a 1 mg/LSB sensitivity. The extreme low power capabilities of the MMA8491Q will reduce the low data rate current consumption to less than 400 n A per Hz. 2 Features and benefits - Extreme low power, 400 n A per Hz - Ultra-fast data output time, ~700 μs - VDD supply range of 1.95 V to 3.6 V - 3 mm x 3 mm, 0.65 mm pitch with visual solder joint inspection - ±8 g full-scale range - 14-bit digital output, 1 mg/LSB sensitivity - Output Data Rate (ODR), implementation based from < 1 Hz to 800 Hz1 - I2C digital interface - 3-axis, 45° tilt outputs 3 Typical applications - Smart grid: tamper detect - Anti-theft - White goods tilt - Remote controls 1 The ODR for this device is user defined by the period of the Enable pulsed signal. The maximum remended frequency of the Enable signal or the ODR that can be achieved for this device is 800 Hz.
