Overview
The ADXRS620BBGZ from Analog Devices Inc. is a complete angular rate sensor (gyroscope) that utilizes the company's surface-micromachining process. This device integrates all necessary electronics on a single chip, making it a functionally complete and cost-effective angular rate sensor. The manufacturing process is the same high-volume BiMOS process used for high-reliability automotive airbag accelerometers. The ADXRS620 is designed for automotive applications and is 100% pin, package, temperature, and function compatible with the industrial grade ADXRS652 gyro.
