FEATURES
GENERAL DESCRIPTION
Triaxial, digital gyroscope
The ADIS16465 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 ADIS16465 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.

SPI-compatible data communications
The ADIS16465 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.
