BMA456 Intelligent, triaxial acceleration sensor
■The BMA456 is an ultra-small, triaxial, low-g high performance acceleration sensor with digital interfaces, aiming for low-power and demanding consumer electronics applications. Featuring 16 bit digital resolution and embedded intelligence, the BMA456 allows low-noise measurement of accelerations in 3 perpendicular axes and thus senses wrist tilt, tab/double tab and enables plqg 'if play step counting especially in wearable devices. The superior temperature behaviour of BMA456 facilitate accurate measurements over changing temperature.
■The reduced height of only 0.65 mm is beneficial for wearable devices.
●SENSOR FEATURES
■With its embedded intelligence BMA456 is unique in the class of consumer grade accelerometers for smart phones, wearable devices and toys and gadgets. The embedded intelligence enables low current step-counting at 25μA. On top, the BMA456 integrates a multitude of other features (e.g. tilt, significant motion etc.) th at facilitate its use especially in the area of Android based smart phones, to fulfill the newest Android M accelerometer requirements. Featuring a high performance measurement mode with low pass filters and a current consumption of only 150 μA the BMA456 is robust to vibrations and aliasing. In low-power mode operation the current consumption can be even further reduced by more than one order of magnitude. This fulfills the current consumption requirements for always-on applications. The BMA456 is highly configurable in order to give the designer full flexibility when integrating the sensor into the system.
