Compact, Precision Six Degrees of Freedom Inertial Sensor Data Sheet ADIS16445 FEATURES GENERAL DESCRIPTION Triaxial digital gyroscope with digital range scaling The ADIS16445 iSensor device is a complete inertial system 62/sec, 125/sec, 250/sec settings that includes a triaxial gyroscope and a triaxial accelerometer. Axis-to-axis alignment, <0.05 Each sensor in the ADIS16445 combines industry-leading Triaxial digital accelerometer, 5 g minimum iMEMS technology with signal conditioning that optimizes Autonomous operation and data collection dynamic performance. The factory calibration characterizes No external configuration commands required each sensor for sensitivity, bias, and alignment. As a result, each 175 ms start-up time sensor has its own dynamic compensation formulas that provide Factory calibrated sensitivity, bias, and axial alignment accurate sensor measurements. Calibration temperature range: 40C to +85C The ADIS16445 provides a simple, cost-effective method for SPI-compatible serial interface integrating accurate, multi-axis inertial sensing into industrial Embedded temperature sensor systems, especially when compared with the complexity and Programmable operation and control investment associated with discrete designs. All necessary motion Automatic and manual bias correction controls testing and calibration are part of the production process at the Bartlett window FIR length, number of taps factory, greatly reducing system integration time. Tight orthogonal Digital I/O: data ready, alarm indicator, general-purpose alignment simplifies inertial frame alignment in navigation systems. Alarms for condition monitoring The serial peripheral interface (SPI) and register structures Enable external sample clock input up to 1.1 kHz provide a simple interface for data collection and configuration Single command self-test control. Single-supply operation: 3.15 V to 3.45 V The ADIS16445 has a compatible pinout for systems that 2000 g shock survivability currently use other Analog Devices, Inc., inertial measurement Operating temperature range: 40C to +105C unit (IMU) products, such as the ADIS16334 or the APPLICATIONS ADIS16485. The ADIS16445 is packaged in a module that is Platform stabilization and control approximately 24.1 mm 37.7 mm 10.8 mm and has a standard Navigation connector interface.
