General description
The BMA250 is a triaxial, low-g acceleration sensor with digital output for consumer market
applications. 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.
