The ADXRS800 is an angular rate sensor (gyroscope) intended for automotive electronic stability control, vehicle rollover detection, and other high performance applications. An advanced, differential, quad-sensor design rejects the influence of linear acceleration, enabling the ADXRS800 to operate in exceedingly harsh environments where shock and vibration are present.
The ADXRS800 uses an internal, continuous self-test archi-tecture. 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 ADXRS800 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 ADXRS800 is available in a cavity plastic SOIC-16 and an SMT-compatible vertical mount package 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).

Shock and Vibration Rejection of MEMS Gyroscopes
The gyroscope demo presents 2 ADI MEMS gyros (ADXRS800, ADXRS450) and 2 competitor gyros. Watch the output of each gyro in response to the applied rate of rotation. Shown is the superior shock and vibration rejection performance of ADI’s gyros.
