描述 Description

The BMA255 is an advanced, ultra-small, triaxial,low-g acceleration sensor with digital interfaces, aiming for low-power consumer electronics applications. Featuring 12 bit digital resolution, the BMA255 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 ultra-small footprint of only 2 mm x 2 mm the BMA255 is unique in the class of low-noise, 12 bit digital acceleration sensors. On top, the BMA255 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. Featuring a full operation current consumption of only 130 µA the BMA255 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. The BMA255 is highly configurable in order to give the designer full flexibility when integrating the sensor into the system.
