FEATURES 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 Innovative ceramic vertical mount package (VMP) provides pitch and roll rate response Qualified for automotive applications APPLICATIONS Electronic stability control High performance platform stabilization GENERAL DESCRIPTION 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).
