Analog Devices Inc. ADXRS453 Digital Output Gyroscope

Analog Devices Inc. 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 Inc. 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.
