Four Degrees of Freedom Inertial Sensor

The ADIS16300 iSensor® is a complete inertial system that includes a yaw rate gyroscope and tri-axis accelerometer. Each sensor in the ADIS16300 combines industry-leading iMEMS® technology with signal conditioning that optimizes dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, alignment, and linear acceleration (gyro bias). As a result, each sensor has its own dynamic compensation for correction formulas that provide accurate sensor measurements over the specified power supply range of +4.75 V to +5.25 V. The ADIS16300 provides a simple, cost-effective method for integrating accurate, multi-axis, 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. An improved SPI interface and register structure provide faster data collection and configuration control. The ADIS16300, along with a flex interface, drops into current systems that use the ADIS1635x family, providing the opportunity to scale cost for systems that only require four degrees of freedom inertial sensing. This compact module is approximately 23 mm × 31 mm × 7.5 mm and provides a standard connector interface, which enables horizontal or vertical mounting.
