FEATURES
GENERAL DESCRIPTION
Triaxial digital gyroscope with digital range scaling
250°/sec, 500°/sec, 1000°/sec settings
Axis-to-axis alignment, <0.05°
Triaxial digital accelerometer, 18 g minimum
Triaxial digital magnetometer, 1.9 gauss minimum
Digital barometer, 10 mbar to 1200 mbar
The ADIS16448 iSensor® device is a complete inertial system
that includes a triaxial gyroscope, a triaxial accelerometer, a
triaxial magnetometer, and pressure sensors. Each sensor in
the ADIS16448 combines industry-leading iMEMS® technology
with signal conditioning that optimizes dynamic performance.
The factory calibration characterizes each sensor for sensitivity,
Calibrated pressure range: 300 mbar to 1100 mbar
Autonomous operation and data collection
No external configuration commands required
205 ms start-up time
Factory calibrated sensitivity, bias, and axial alignment
Calibration temperature range: −40°C to +70°C
SPI-compatible serial interface
bias, alignment, and linear acceleration (gyroscope bias). As a
result, each sensor has its own dynamic compensation formulas
that provide accurate sensor measurements.
The ADIS16448 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 structures provide a simple interface for
data collection and configuration control.
Embedded temperature sensor
Programmable operation and control
Automatic and manual bias correction controls
Bartlett window FIR length, number of taps
Digital I/O: data ready, alarm indicator, general-purpose
Alarms for condition monitoring
The ADIS16448 has a compatible pinout for systems that currently
use other Analog Devices, Inc., IMU products (ADIS163xx/
ADIS164xx). The ADIS16448 is packaged in a module that is
approximately 24.1 mm × 37.7 mm × 10.8 mm and has a standard
connector interface.
