Analog Devices Introduces ADXRS450, iMEMS Gyroscope for Angular Rate Sensing in Harsh Environments.
The ADXRS450 is high-performance and , low-power iMEMS gyroscope with digital output specifically for angular rate (rotational) sensing in harsh environments. The ADXRS450 intended for Industrial, Medical, Instrumentation, Stabilization and other high performance applications. An advanced, differential, quad-sensor design rejects the influence of linear acceleration, enabling the ADXRS450 to operate in exceedingly harsh environments where shock and vibration are present. The ADXRS450 utilizes an internal, continuous self test architecture. The integrity of the electromechanical system is checked by applying a high frequency electrostatic force to the sense structure in order to generate a rate signal which can be differentiated from the baseband rate data and internally analyzed. The ADXRS450 is capable of sensing angular rate up to ±300°/sec. Angular rate data is presented as a 16-bit word, as part of a 32-bit SPI message. The ADXRS450 is available in a cavity plastic SOIC-16 and an SMT-compatible vertical mount package and is capable of operating across both a wide voltage range (3.3V to 5V) and temperature range (-40°C to 105°C)…
