Precision MEMS IMU offers a simplified method for industrial systems

Analog Devices ADIS16505 Precision, Miniature Microelectomechanical System, Inertial Measurement Unit comprises a triaxial gyroscope and a triaxial accelerometer. The IMU presents an uncomplicated, cost-effective method for integrating accurate, multiaxis inertial sensing into industrial systems.

The MEMS IMU provides inertial sensors that combine with signal conditioning optimises dynamic performance. The factory calibration distinguishes each sensor for bias, sensitivity, alignment, linear acceleration (gyroscope bias), and point of percussion (accelerometer location). Subsequently, each sensor allows dynamic compensation formulas, that offer accurate sensor measurements over a large set of conditions.

All required motion testing and calibration are elements of the production process at the factory, allowing system integration time to be greatly reduced. Tight orthogonal alignment alleviates inertial frame alignment in navigation systems. The SPI and register structure provide a simple interface for data collection and configuration control.

The device is offered in a 100-ball, BGA package that is an approximate size of 15mm x 15mm x 5mm.
