Analog Devices Inc. ADIS16445 iSensor MEMS IMU

Analog Devices ADIS16445 iSensor® device is designed as a complete inertial system that consists of a triaxial gyroscope and a triaxial accelerometer. Each sensor in the ADIS16445 integrates industry-leading iMEMS® technology with signal conditioning that optimizes dynamic performance. The factory calibration measures each sensor for sensitivity, bias, alignment, and linear acceleration (gyroscope bias). As a result, each sensor has its own dynamic compensation formulas that provide accurate sensor measurements. Using the ADIS16445, designers have a simple, cost-effective method for integrating accurate, multiaxis inertial sensing into industrial systems. 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 ADIS16445 iSensor® device is ideal for platform stabilization & control, navigation, and robotics applications.
