It allows measurements of acceleration in three perpendicular axes. An evaluation circuitry (ASIC) converts the output of a micromechanical acceleration-sensing structure (MEMS) that works according to the differential capacitance principle. Package and interface have been defined to match a multitude of hardware requirements. Since the sensor Features an ultra-small footprint and a flat package it is ingeniously suited for mobile...
