FEATURES
GENERAL DESCRIPTION
Triaxial, digital gyroscope, ±100°/sec dynamic range
The ADIS16490 is a complete inertial system that includes a
±0.05° axis to axis misalignment error
triaxis gyroscope and a triaxis accelerometer. Each inertial sensor
±0.25° axis to package misalignment error
in the ADIS16490 combines industry leading iMEMS® technology
1.8°/hr in run bias stability
with signal conditioning that optimizes dynamic performance.
0.09°/√hr angular random walk
The factory calibration characterizes each sensor for sensitivity,
Triaxial, digital accelerometer, ±8 g
bias, alignment, and linear acceleration (gyroscope bias). As a
3.6 μg in run bias stability
result, each sensor has its own dynamic compensation formulas that
Triaxial, delta angle and delta velocity outputs
provide accurate sensor measurements.

APPLICATIONS
Precision instrumentation, stabilization
The ADIS16490 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 structure provide a
simple interface for data collection and configuration control.
The ADIS16490 uses the same footprint and connector system as
the ADIS16375, ADIS16480, ADIS16485, and ADIS16488A, which
greatly simplifies the upgrade process. The ADIS16490 is packaged
in a module that is approximately 47 mm × 44 mm × 14 mm
and includes a standard connector interface.
