Compact, Precision Ten Degree of Freedom Inertial Sensor

The ADIS16448 iSensor® device is a complete inertial system that includes a triaxial gyroscope, a triaxial accelerometer, a triaxial magnetometer, and pressure sensors. Each sensor in the ADIS16448 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 ADIS16448 provides a simple, cost-effective method for integrating accurate, multiaxis 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 SPI and register structures provide a simple interface for data collection and configuration control.

The ADIS16448 has a compatible pinout for systems that currently use other Analog Devices, Inc., IMU products, such as ADIS16334 or ADIS16485. The ADIS16448 is packaged in a module that is approximately 24.1 mm × 37.7 mm × 10.8 mm and has a standard connector interface.
