The ADXRS453 is an angular rate sensor (gyroscope) intended for industrial, instrumentation, and stabilization applications in high vibration environments. An advanced, differential, quad sensor design rejects the influence of linear acceleration, enabling the ADXRS453 to offer high accuracy rate sensing in harsh envi-ronments where shock and vibration are present.
The ADXRS453 uses an internal, continuous self-test architec-ture. 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 base-band rate data and internally analyzed.
The ADXRS453 is capable of sensing an angular rate of up to ±300°/sec. Angular rate data is presented as a 16-bit word that is part of a 32-bit SPI message.
The ADXRS453 is available in a 16-lead plastic cavity SOIC (SOIC_CAV) and an SMT-compatible vertical mount package (LCC_V), and is capable of operating across a wide voltage range (3.3 V to 5 V).
