Overview
The ADXRS646TBGZ-EP is a high-performance angular rate sensor (gyroscope) produced by Analog Devices Inc. This device is designed to offer excellent vibration immunity and is particularly suited for applications in harsh environments where shock and vibration are prevalent. The ADXRS646TBGZ-EP features a low bias drift of 12°/hr (typical) and superior acceleration and vibration rejection, making it ideal for rate sensing in severe mechanical environments. It is manufactured using Analog Devices' patented high-volume BiMOS surface-micromachining process and includes an advanced, differential, quad sensor design for enhanced performance.
