Data Sheet Compact, Precision Six Degrees of Freedom Inertial Sensor 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: −40°C to +85°C SPI-compatible serial interface Embedded temperature sensor Programmable operation and control Automatic and manual bias correction controls Bartlett window FIR length, number of taps Digital I/O: data ready, alarm indicator, general-purpose Alarms for condition monitoring Enable external sample clock input up to 1.1 kHz Single command self-test Single-supply operation: 3.15 V to 3.45 V The ADIS16445 provides a simple, cost-effective method for integrating accurate, multi-axis inertial sensing into industrial systems, especially when compared with the complexity and investment associated with discrete designs. All necessary motion testing and calibration are part of the production process at the factory, greatly reducing system integration time. Tight orthogonal alignment simplifies inertial frame alignment in navigation systems. The serial peripheral interface (SPI) and register structures provide a simple interface for data collection and configuration control. 2000 g shock survivability The ADIS16445 has a compatible pinout for systems that Operating temperature range: −40°C to +105°C currently use other Analog Devices, Inc., inertial measurement APPLICATIONS unit (IMU) products, such as the ADIS16334 or the 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.
