Seven Degrees of Freedom Inertial Sensor Data Sheet ADIS16489 FEATURES GENERAL DESCRIPTION Triaxial, digital gyroscope, ±450°/sec dynamic range
The ADIS16489 is a complete inertial system that includes a
±0.018° axis-to-axis misalignment error
triaxis gyroscope, a triaxis accelerometer, and a barometer. Each
5.3°/hr in-run bias stability
inertial sensor in the ADIS16489 combines industry leading
0.25°/√hr angular random walk
iMEMS® technology with signal conditioning that optimizes
0.045°/sec nonlinearity
dynamic performance. The factory calibration characterizes
Triaxial, digital accelerometer, ±18 g dynamic range
each sensor for sensitivity, bias, alignment, and linear acceleration
Barometer, 300 mbar to 1100 mbar
(gyroscope bias). As a result, each sensor has its own dynamic
Triaxial, delta angle and delta velocity outputs
compensation formulas that provide accurate sensor

measurements.
Calibration temperature range: −40°C to +85°C
The ADIS16489 provides a simple, cost effective method for
SPI compatible
integrating accurate, multiaxis inertial sensing into industrial
Programmable operation and control
systems, especially when compared with the complexity and
Automatic and manual bias correction controls
investment associated with discrete designs. All necessary motion

navigation systems. The serial peripheral interface (SPI) and
Optional input sync clock: up to 2.4 kHz

greatly simplifies the upgrade process. The ADIS16489 is packaged in a module that is approximately 44 mm × 47 mm × 14 mm
Platform stabilization and control
and includes a standard connector interface.
