Datasheet ADIS16497 (Analog Devices)

Tactical Grade, Six Degrees of Freedom Inertial Sensor Data Sheet ADIS16497 FEATURES GENERAL DESCRIPTION Triaxial, digital gyroscope
The ADIS16497 is a complete inertial system that includes a
±125°/sec, ±450°/sec, ±2000°/sec range options
triaxis gyroscope and a triaxis accelerometer. Each inertial sensor
±0.05° axis to axis misalignment error
in the ADIS16497 combines industry leading iMEMS® technology
±0.25° (maximum) axis to package misalignment error
with signal conditioning that optimizes dynamic performance.
0.8°/hr in-run bias stability
The factory calibration characterizes each sensor for sensitivity,
0.09°/√hr angular random walk
bias, alignment, and linear acceleration (gyroscope bias). As a
Triaxial, digital accelerometer, ±40 g
result, each sensor has its own dynamic compensation formulas that
13 μg in run bias stability
provide accurate sensor measurements.
Triaxial, delta angle and delta velocity outputs
The ADIS16497 provides a simple, cost effective method for
Factory calibrated sensitivity, bias, and axial alignment
integrating accurate, multiaxis inertial sensing into industrial
Calibration temperature range: −40°C to +85°C
systems, especially when compared with the complexity and
SPI compatible
investment associated with discrete designs. All necessary motion
Programmable operation and control
testing and calibration are part of the production process at
Automatic and manual bias correction controls
the factory, greatly reducing system integration time. Tight
Configurable FIR filters
orthogonal alignment simplifies inertial frame alignment in
Digital I/O: data ready, external clock
navigation systems. The serial peripheral interface (SPI) and
Sample clock options: internal, external, or scaled
register structure provide a simple interface for data col ection
On demand self test of inertial sensors
and configuration control.
Single-supply operation: 3.0 V to 3.6 V 1500 g mechanical shock survivability
The footprint and connector system of the ADIS16497 enable a
Operating temperature range: −40°C to +105°C
simple upgrade from the ADIS16375, ADIS16480, ADIS16485, ADIS16488A, and ADIS16490. The ADIS16497 is available in an
APPLICATIONS
aluminum package that is approximately 47 mm × 44 mm ×
Precision instrumentation, stabilization
14 mm and includes a standard connector interface.
