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 ADIS16445 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 ADIS16445 has a compatible pinout for systems that cur-
rently use other Analog Devices, Inc., IMU products, such as
the ADIS16334 or the ADIS16485. The ADIS16445 is packaged
