General Description
The BMG160 is a 3-axis angular rate sensor that is made of a surface micro machined sensing
element and an evaluation ASIC.
Both parts are packed into one single LGA 3.0mm x 3.0mm x 0.95mm housing.
The BMG160 is designed to meet requirements for consumer applications such as image
stabilization (DSC and camera-phone), gaming and pointing devices. It is capable to measure
angular rates in three perpendicular room dimensions, the x-, y- and z-axis, and to provide the
corresponding output signals. The BMG160 is fitted with digital bi-directional SPI and I
2
C
interfaces for optimum system integration.
The BMG160 offers a variable V
DDIO
voltage range from 1.2V to 3.6V and can be programmed
to optimize functionality, performance and power consumption in customer specific applications.
In addition it features an on-chip interrupt controller enabling motion-based applications without
use of a microcontroller.
