Tactical Grade, Six Degrees of Freedom Inertial Sensors

The ADIS16545/ADIS16547 are a complete inertial system that includes a triaxis gyroscope and a triaxis accelerometer. Each inertial sensor in the ADIS16545/ADIS16547 combines 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 ADIS16545/ADIS16547 provide 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 and precision alignment features simplify inertial frame alignment in navigation systems. The serial peripheral interface (SPI) and register structure provide a simple interface for data collection and configuration control.

The footprint and connector system of the ADIS16545/ADIS16547 enable a simple upgrade from the ADIS16488A, ADIS16495 and ADIS16497. Note, however, that there is a small difference in sample rate between the ADIS16495 and the ADIS16545/ADIS16547 if the internal oscillator is used. The same small difference in sample rate exists between the ADIS16497 and the ADIS16545/ ADIS16547. Refer to the Specifications section for details about the native sample rate. The ADIS16545/ADIS16547 are available in an aluminum package that is approximately 47 mm × 44 mm × 14 mm and includes a standard connector interface.
