Description
AI
The ADIS16470 is a miniature MEMS inertial measurement unit (IMU) that includes a triaxial gyroscope and a triaxial accelerometer. Each inertial sensor in the ADIS16470 combines with signal conditioning that optimizes dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, alignment, linear acceleration (gyroscope bias), and point of percussion (accelerometer location). As a result, each sensor has dynamic compensation formulas that provide accurate sensor measurements over a broad set of conditions.The ADIS16470 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 serial peripheral interface (SPI) and register structure provide a simple interface for data collection and configuration control.The ADIS16470 is in a 44-ball, ball grid array (BGA) package that is approximately 11 mm × 15 mm × 11 mm.ApplicationsNavigation, stabilization, and instrumentationUnmanned and autonomous vehiclesSmart agriculture/construction machineryFactory/industrial automation, roboticsVirtual/augmented realityInternet of Moving Things
