The BMA280 is an advanced, ultra-small, triaxial, low-g acceleration sensor with digital interfaces, aiming for low-power consumer electronics applications. Featuring 14 bit digital resolution, the BMA280 allows very low-noise measurement of accelerations in 3 perpendicular axes and thus senses tilt, motion, shock and vibration in cellular phones, handhelds, computer peripherals, man-machine interfaces, virtual reality features and game controllers.
With its small footprint of only 2 x 2 mm² the BMA280 is unique in the class of low-noise, 14 bit digital acceleration sensors. On top, the BMA280 integrates a multitude of features that facilitate its use especially in the area of motion detection applications, such as device orientation detection, gaming, HMI and menu browser control. Navigation and spirit level measurement applications are enabled by the 14 bit resolution. Featuring a full operation current consumption of only 130 µA the BMA280 is ideally suited for mobile consumer electronic devices. In low-power mode operation the current consumption can be even further reduced by more than one order of magnitude.
