High Performance, SPI Digital Output, Angular Rate Sensor

The ADXRS810 is an angular rate sensor (gyroscope) intended for automotive navigation applications. An advanced, differential, quad-sensor design rejects the influence of linear acceleration, enabling the ADXRS810 to operate in exceedingly harsh environments where shock and vibration are present.

The ADXRS810 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 baseband rate data and internally analyzed.

The ADXRS810 is capable of sensing an angular rate of up to ±300°/sec. Angular rate data is presented as a 16-bit word, as part of a 32-bit SPI message.

The ADXRS810 is available in a cavity plastic SOIC-16 and is capable of operating across both a wide voltage range (3.3 V to 5 V) and temperature range (−40°C to 105°C).
