Overview
The ADXRS646TBGZ-EP-RL, produced by Analog Devices Inc., is a high-performance angular rate sensor (gyroscope) designed to offer excellent vibration immunity and low noise. This device is particularly suited for applications in harsh environments where shock and vibration are prevalent. The ADXRS646 uses Analog Devices' patented high-volume BiMOS surface-micromachining process and features an advanced, differential, quad sensor design that enhances acceleration and vibration rejection. The gyroscope provides a voltage output proportional to the angular rate about the axis normal to the top surface of the package, with a minimum measurement range of ±250°/sec.
