Overview
The ADXRS649BBGZ is a high-performance, low-power angular rate sensor (gyroscope) produced by Analog Devices Inc. This device utilizes Analog Devices' patented high volume BiMOS surface-micromachining process to integrate a complete gyro on a single chip. The ADXRS649 is designed to sense angular rate about the z-axis (yaw) and features an advanced, differential, quad sensor design that rejects the influence of linear acceleration, making it suitable for harsh environments with shock and vibration. The sensor offers ultrafast startup, low power consumption, and a wide dynamic range, making it ideal for various motion-sensing applications.
