Compact, Precision Six Degrees of Freedom Inertial Sensor

The ADIS16445 iSensor® device is a complete inertial system that includes a triaxial gyroscope and a triaxial accelerometer. Each sensor in the ADIS16445 combines industry-leading iMEMS® technology with signal conditioning that optimizes dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, and alignment. As a result, each sensor has its own dynamic compensation formulas that provide accurate sensor measurements.

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.

The ADIS16445 has a compatible pinout for systems that currently use other Analog Devices, Inc., inertial measurement unit (IMU) products, such as the ADIS16334 or the ADIS16485. The ADIS16445 is packaged in a module that is approximately 24.1 mm × 37.7 mm × 10.8 mm and has a standard connector interface.
