The new ADXRS453 from Analog Devices is an angular rate sensor (gyroscope) intended for Industrial, Medical, Instrumentation, Stabilization and other applications. The ADXRS453 is capable of sensing angular rate up to ±300°/sec, according to the company. Its differential, quad-sensor design is said to reject the influence of linear acceleration, enabling the ADXRS453 to operate in exceedingly harsh environments where shock and vibration are present. Sensitivity to linear acceleration is specified at only 0.01°/sec/g, vibration rectification is 0.0002°/sec/g2 and power consumption is stated as 6 milliamps under typical conditions.
The ADXRS453 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 to generate a rate signal which can be differentiated from the baseband rate data and internally analyzed.
Production release is scheduled for December 2010.
