Six Degrees of Freedom Inertial Sensor

The ADIS16486 is a complete inertial system that includes a triaxis gyroscope and a triaxis accelerometer. Each inertial sensor in the ADIS16486 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 (gyroscope bias). Therefore, each sensor has dynamic compensation formulas that provide accurate sensor measurements.

The ADIS16486 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, which reduces 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. Parylene coating of all internal circuitry provides a protective barrier against moisture exposure.

The ADIS16486 uses the same footprint and connector system as the ADIS16480, ADIS16485, ADIS16487, and ADIS16488A, which greatly simplifies the upgrade process. The ADIS16486 is packaged in a module that is approximately 47 mm × 44 mm × 14 mm with a 24-lead standard connector interface.
