Overview
The ADXRS450BEYZ, produced by Analog Devices Inc., is a high-performance angular rate sensor (gyroscope) designed for various demanding applications. This device is part of the ADXRS450 series and is known for its advanced differential, quad sensor design that effectively rejects the influence of linear acceleration. This makes it highly suitable for environments where shock and vibration are present. The ADXRS450BEYZ operates across a wide temperature range of −40°C to +105°C and can sense angular rates up to ±300°/sec.
