NORWOOD, USA: Analog Devices Inc. (ADI) 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.
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 ADXRS453 is well suited for industrial and defense applications.
“The ADXRS453 features an innovative Quad-Sensor design that rejects the influence of linear acceleration caused by intense shock and vibration,” said Kelly Atkinson, defense electronics marketing manager, Analog Devices.
“This enables the ADXRS453 to enable complex navigation and GPS-aided dead-reckoning in exceedingly harsh environments like unmanned aerial vehicles (UAVs), platform stabilization in land- and sea-based military vehicles, and avionics equipment where shock and vibration are present and can cause measurement errors in less capable gyros.”
