FEATURES
GENERAL DESCRIPTION
Triaxial, digital gyroscope
The ADIS16497 is a complete inertial system that includes a
triaxis gyroscope and a triaxis accelerometer. Each inertial sensor
in the ADIS16497 combines industry leading iMEMS® technology
125°/sec, 450°/sec, 2000°/sec range options
0.05° axis to axis misalignment error
0.25° (maximum) axis to package misalignment error
0.8°/hr in-run bias stability
0.09°/√hr angular random walk
Triaxial, digital accelerometer, 40 g
13 μg in run bias stability
with signal conditioning that optimizes dynamic performance.
The factory calibration characterizes each sensor for sensitivity,
bias, alignment, and linear acceleration (gyroscope bias). As a
result, each sensor has its own dynamic compensation formulas that
provide accurate sensor measurements.

The ADIS16497 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 serial peripheral interface (SPI) and
register structure provide a simple interface for data collection
and configuration control.
The footprint and connector system of the ADIS16497 enable a
simple upgrade from the ADIS16375, ADIS16480, ADIS16485,
ADIS16488A, and ADIS16490. The ADIS16497 is available in an
aluminum package that is approximately 47 mm × 44 mm ×
14 mm and includes a standard connector interface.
