MEMS gyroscope designed for harsh conditions
October 01, 2010 // Phil Ling
Analog Devices has introduced the ADXRS453 iMEMS gyroscope, the latest addition to ADI's portfolio of fourth-generation high-performance, low-power gyroscopes with digital output. Specifically designed for angular rate (rotational) sensing in harsh environments, the new gyro features an advanced, differential Quad-Sensor design that enables it to operate accurately under intense shock and vibration conditions.
ADI claims the ADXRS453 is the most stable, vibration-immune MEMS gyro available, with sensitivity to linear acceleration specified at only 0.01°/sec/g, vibration rectification of only 0.0002°/sec/g2, a noise-rate density specification of 0.023°/sec/√Hz at +105°C, null offset stability of 16°/hr and power consumption of only 6 milliamps under typical conditions.
The new gyro is available in a cavity plastic SOIC-16 and an SMT-compatible vertical mount package and is capable of operating across a wide voltage range of 3.3 V to 5 V and an extended temperature range of -40°C to 125°C.
The digital output ADXRS453 is capable of sensing angular rates up to ±300°/sec and its angular rate data is presented as a 16-bit word within a 32-bit serial peripheral interface (SPI) message. 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 that can be differentiated from the baseband rate data and internally analyzed.
The high-performance ADXRS453 and ADXRS450 iMEMS gyroscopes are available today in sample quantities with production release scheduled for December 2010.All news
