Analog Devices Inc. ADXRS800 高性能角速度陀螺仪

Analog Devices ADXRS800 角速度传感器陀螺仪专门设计用于汽车电子稳定控制、车辆滚动检测和各种高性能应用。 ADXRS800 先进的差分四传感器设计可抑制线性加速度的影响。这使得 ADXRS800 能够在极其恶劣的冲击和振动环境中工作。 ADXRS800 采用内部连续自测架构，确保在严苛的环境中发挥高度可靠的性能。设计人员对检测结构施加一个高频静电力以便产生一个速率信号来检查机电系统的完整性。然后，将该速率信号与基带速率数据区分开来，并进行内部分析。 ADXRS800 陀螺仪能够检测高达 ±300°/s 的角速率。角速率数据以 16 位字的形式提供，作为 32 位 SPI 消息的一部分。 ADXRS800 陀螺仪能够在 3.3V 至 5V 的宽电压范围内和 −40°C 至 +105°C 的温度范围内工作。

Designers can check the integrity of the electromechanical system by applying a high frequency electrostatic force to the sense structure to generate a rate signal. The rate signal can then be differentiated from the baseband rate data and internally analyzed. The ADXRS800 gyroscope is capable of sensing an angular rate of up to±300°/sec. The angular rate data is generated as a 16-bit word, and as part of a 32-bit SPI message. The ADXRS800 gyroscope operates across a wide 3.3V-5V voltage range and −40°C to +105°C temperature range.
