High Performance, SPI Digital Output, Angular Rate Sensor Data Sheet ADXRS800 FEATURES GENERAL DESCRIPTION Excellent null offset stability over temperature The ADXRS800 is an angular rate sensor (gyroscope) intended High vibration rejection over a wide frequency range for automotive electronic stability control, vehicle rollover 2000 g powered shock survivability detection, and other high performance applications. An advanced, SPI digital output with 16-bit data-word differential, quad-sensor design rejects the influence of linear Low noise acceleration, enabling the ADXRS800 to operate in exceedingly Continuous self-test harsh environments where shock and vibration are present. Fail-safe functions The ADXRS800 uses an internal, continuous self-test archi- Temperature sensor tecture. The integrity of the electromechanical system is checked 3.3 V and 5 V operation by applying a high frequency electrostatic force to the sense 40C to +105C operation structure to generate a rate signal that can be differentiated Small, low-profile industry standard SOIC package provides from the baseband rate data and internally analyzed. yaw rate (Z-axis) response The ADXRS800 is capable of sensing an angular rate of up to Innovative ceramic vertical mount package (VMP) provides 300/sec. Angular rate data is presented as a 16-bit word, as pitch and roll rate response part of a 32-bit SPI message. Qualified for automotive applications The ADXRS800 is available in a cavity plastic SOIC-16 and APPLICATIONS an SMT-compatible vertical mount package and is capable of Electronic stability control operating across both a wide voltage range (3.3 V to 5 V) and High performance platform stabilization temperature range (40C to +105C).
