GENERAL DESCRIPTION
The ADIS16460 iSensor® device is a complete inertial system
that includes a triaxial gyroscope and a triaxial accelerometer.
Each sensor in the ADIS16460 combines industry leading
iMEMS® technology with signal conditioning that optimizes
dynamic performance. The factory calibration characterizes
each sensor for sensitivity, bias, and alignment. As a result, each
sensor has its own dynamic compensation formulas that provide
accurate sensor measurements.
The ADIS16460 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, greatly reducing system integration time. 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 ADIS16460 is in an aluminum module package that is
approximately 22.4 mm × 22.4 mm × 9 mm and has a 14-pin
connector interface.
