ADXRS810

Data Sheet FEATURES High Performance, SPI Digital Output, Angular Rate Sensor ADXRS810 GENERAL DESCRIPTION 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 16-lead SOIC 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). Excellent null offset stability over temperature High vibration rejection over a wide frequency range 2000 g powered shock survivability SPI digital output with 16-bit data-word Low noise Continuous self-test Fail-safe functions Temperature sensor 3.3 V and 5 V operation −40°C to +105°C operation Small, low profile, industry standard SOIC package provides yaw rate (Z-axis) response Qualified for automotive applications APPLICATIONS Car navigation FUNCTIONAL ...
