Analog Devices Inc. ADXRS453 Digital Output Gyroscope

Analog Devices ADXRS453 Digital Output Gyroscope is an angular rate sensor optimized 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 environments where shock and vibration are present. 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 uses 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 base-band rate data and internally analyzed.

The Analog Devices ADXRS453 is offered in a 16-lead plastic cavity Small Outline Integrated Circuit (SOIC) package, ideal for Yaw Rate (z-axis) sensing. The ADXRS453 is also available in an innovative SMT-compatible vertical mount Leadless Chip Carrier (LCC) package, which can be oriented for Pitch, Roll, or Yaw response without the need for additional boards mounted at 90°. Both package options are Pb-free and RoHS-compliant.
