Analog Devices Inc. ADIS16500 Precision Miniature MEMS IMU
Analog Devices Inc. ADIS16500 Precision, Miniature MEMS IMU (Inertial Measurement Unit) includes a triaxial gyroscope and a triaxial accelerometer. Each inertial sensor combines with signal conditioning to optimize dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, alignment, linear acceleration (gyroscope bias), and point of percussion (accelerometer location). Each sensor has dynamic compensation formulas for accurate sensor measurements over a broad set of conditions.
The ADIS16500 is a 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 ADIS16500 is available in a 100-ball, ball grid array (BGA) package that is approximately 15mm x 15mm × 5mm.
