The ADXRS300 is a 300 deg/sec angular rate sensor (gyroscope) on a single chip, complete with all of the required electronics. The sensor is built using Analog Devices' proprietary iMEMS® surface micromachining process, the same proven technology that has enabled the company to ship over 100 million inertial sensors. Two polysilicon sensing structures each contain a dither frame which is electrostatically driven to resonance. A rotation about the z axis, normal to the plane of the chip, produces a Coriolis force which displaces the sensing structures perpendicular to the vibratory motion. This Coriolis motion is detected by a series of capacitive pickoff structures on the edges of the sensing structures. The resulting signal is amplified and demodulated to produce the rate signal output. The device is the only commercially available gyro to integrate a digitally controlled, full self-test feature that can be operated while the sensor is active. It includes a temperature sensor for easy-to-implement temperature coefficient calibration, as well as a precision voltage reference. It operates from 5V supply over the industrial temperature range of -40°C to +85°C and is available in a space-saving 32-pin Ball Grid Array surface-mount package measuring a mere 7mm x 7mm x 3mm.

Application Notes (4)
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
