80/sec Yaw Rate Gyroscope with SPI ADIS16080 FEATURES GENERAL DESCRIPTION Complete angular rate gyroscope The ADIS16080 is a gyroscope that uses the Analog Devices, Z-axis (yaw rate) response Inc. surface-micromachining process to make a functionally SPI digital output interface complete angular rate sensor with an integrated serial periph- High vibration rejection over wide frequency eral interface (SPI). 2000 g-powered shock survivability Externally controlled self-test The digital data available at the SPI port is proportional to the Internal temperature sensor output angular rate about the axis that is normal to the top surface of Dual auxiliary 12-bit ADC inputs the package (see Figure 20). A single external resistor can be Absolute rate output for precision applications used to increase the measurement range. An external capacitor 5 V single-supply operation can be used to lower the bandwidth. 8.2 mm 8.2 mm 5.2 mm package Access to an internal temperature sensor measurement is RoHS compliant provided, through the SPI, for compensation techniques. APPLICATIONS Two pins are available for the user to input analog signals for digitization. An additional output pin provides a precision Platform stabilization voltage reference. Two digital self-test inputs electromechanically Image stabilization excite the sensor to test the operation of the sensor and the Guidance and control signal-conditioning circuits. Inertia measurement units Robotics The ADIS16080 is available in an 8.2 mm 8.2 mm 5.2 mm, 16-terminal, peripheral land grid array (LGA) package.
