General description
The BMA020 is a triaxial, low-g acceleration sensor IC with digital output for consumer market
applications. It allows measurements of acceleration 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.
Package and interface have been defined to match a multitude of hardware requirements. Since
the sensor IC has small footprint and flat package it is attractive for mobile applications. The
sensor IC can be programmed to optimize functionality, performance and power consumption in
customer specific applications.
The BMA020 senses tilt, motion and shock vibration in cell phones, handhelds, computer
peripherals, man-machine interfaces, virtual reality features and game controllers.
