Three-Axis digital gyroscope for mobiles

STMicroelectronics has launched a three-axis digital gyroscope that employs a single sensing structure for motion measurement along all three orthogonal axes . This innovative design approach significantly increases accuracy and reliability in motioncontrolled consumer applications. Existing three-axis-gyroscope solutions rely on two or three independent sensing structures, even if they are on the same silicon substrate; ST’s concept of sensing all three axes with a single driving mass eliminates any interference between the axes that inherently affects and degrades the output signal. The sensor and the ASIC occupy a 4x4x1-mm package and offer userprogrammable full-scale ranges from ±250 dps (degrees per second) up to ±2000 dps, the low full-scale values being for high accuracy of slow-motion sensing, and the high range for detecting and measuring very fast gestures and movements. The device provides a 16-bit data output, together with additional embedded digital features, such as configurable low- and high-pass filters.
