The new gyroscope is extremely lightweight and provides a bias stability of 3.5° per hour and consumes power of less than one watt. The sensor is capable of automatic operation without the intervention of users and provides accurate rate sensing data. Due to the precise output from the sensor, it is best suited for applications where precision is mandatory such as robotics, medical instrumentation, navigation, platform stabilization and control.
The senior business development manager at Analog Devices claims that the new sensor’s performance meets stability and angular random walk specifications, which have so far been possible only by expensive fiber optic sensors. He added that the sensor is able to provide linearity, which is two times than what was previously achieved, starts up 30 times faster and consumes 5 times less power. He stated that the compact size of the sensor makes it suitable for applications that demand precise angular rate sensing. The sensor is developed by integrating MEMS technology with the rich signal conditioning expertise from ADI. The sensor is capable of providing a maximum data rate of 2048 SPS and an averaging/decimation filter structure for optimizing the noise and bandwidth trade-offs. For applications on embedded processor platforms, the sensor is built with a serial peripheral interface (SPI) and a user register for hassle free access to configuration controls and the sensor data calibrated. The bandwidth of the sensor is around 380 hertz, which is suitable for applications involving complex stabilizations. The other physical features of the sensor are 24-pin, dual row, provision of four holes and a pitch connector of 1 mm thickness for connecting to electrical equipment or PCBs. The sensor has an operating temperature range of -40°C to +85°C.
