GENERAL DESCRIPTION
The ADIS16467 is a precision, microelectric mechanical system
(MEMS), inertial measurement unit (IMU) that includes a triaxial
gyroscope and a triaxial accelerometer. Each inertial sensor in the
ADIS16467 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). Therefore, each sensor has dynamic
compensation formulas that provide accurate sensor
measurements over a broad set of conditions.
The ADIS16467 provides a simple, cost effective method for
integrating accurate, multiaxis inertial sensing into industrial
systems, especially when compared to 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 ADIS16467 is in an aluminum module package that is
approximately 22.4 mm × 24.3 mm × 9 mm with a 14-lead
connector interface.
