The BMA150 is an LGA packaged triaxial, low-g acceleration sensor with digital output. Offering many smart functional features the BMA150 is aimed for consumer market applications. It allows measurements of accelerations in three perpendicular axes. An evaluation circuitry converts the output of a three-channel micromechanical acceleration sensing structure that works according to the differential capacitance principle.
The modular ASIC design provides a flexibility to react quickly to customer needs for additional sensor functionality in the future. The BMA150 package and interface have been defined to match a multitude of hardware requirements.
Since the sensor has a flat, small footprint package it is attractive for mobile applications. The sensor can be programmed to optimize functionality, performance and power consumption in customer specific applications.
