BMA150
Digital, triaxal acceleration sensor
Bosch Sensortec
General description
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 3 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 base of the micromachining technology has
proven its capability in more than 100 million Bosch
accelerometers and gyroscopes so far. 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 defi-
ned 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, perfor-
mance and power consumption in customer specific
applications.
