Tactical Grade, Six Degrees of Freedom Inertial Sensor Data Sheet ADIS16490 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.
Factory calibrated sensitivity, bias, and axial alignment
The ADIS16490 provides a simple, cost effective method for
Calibration temperature range: −40°C to +85°C
integrating accurate, multiaxis inertial sensing into industrial
Serial peripheral interface (SPI) compatible
systems, especially when compared with the complexity and
Programmable operation and control
investment associated with discrete designs. All necessary motion
Automatic and manual bias correction controls
testing and calibration are part of the production process at
4 finite impulse response (FIR) filter banks,
the factory, greatly reducing system integration time. Tight
120 configurable taps
orthogonal alignment simplifies inertial frame alignment in
Digital input/output (I/O): data ready, external clock
navigation systems. The SPI and register structure provide a
Sample clock options: internal, external, or scaled
simple interface for data collection and configuration control.
On demand self test of inertial sensors Single-supply operation: 3.0 V to 3.6 V
The ADIS16490 uses the same footprint and connector system as
2000 g shock survivability
the ADIS16375, ADIS16480, ADIS16485, and ADIS16488A, which
Operating temperature range: −40°C to +105°C
greatly simplifies the upgrade process. The ADIS16490 is packaged in a module that is approximately 47 mm × 44 mm × 14 mm
