Compact, Precision Ten Degrees of Freedom Inertial Sensor Data Sheet ADIS16448 FEATURES GENERAL DESCRIPTION Triaxial digital gyroscope with digital range scaling
The ADIS16448 iSensor® device is a complete inertial system
±250°/sec, ±500°/sec, ±1000°/sec settings
that includes a triaxial gyroscope, a triaxial accelerometer, a
Axis-to-axis alignment, <0.05°
triaxial magnetometer, and pressure sensors. Each sensor in
Triaxial digital accelerometer, ±18 g minimum
the ADIS16448 combines industry-leading iMEMS® technology
Triaxial digital magnetometer, ±1.9 gauss minimum
with signal conditioning that optimizes dynamic performance.
Digital barometer, 10 mbar to 1200 mbar
The factory calibration characterizes each sensor for sensitivity,
Calibrated pressure range: 300 mbar to 1100 mbar
bias, and alignment. As a result, each sensor has its own dynamic

205 ms start-up time
The ADIS16448 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 serial interface
investment associated with discrete designs. All necessary motion
Burst mode read sequence with optional CRC-16
testing and calibration are part of the production process at the
Embedded temperature sensor
factory, greatly reducing system integration time. Tight orthogonal
Programmable operation and control
alignment simplifies inertial frame alignment in navigation systems.
Automatic and manual bias correction controls
The SPI and register structures provide a simple interface for
Bartlett window FIR length, number of taps
data col ection and configuration control.
Digital I/O: data ready, alarm indicator, general-purpose Alarms for condition monitoring
The ADIS16448 has a compatible pinout for systems that currently
Enable external sample clock input up to 1.1 kHz
use other Analog Devices, Inc., IMU products, such as
Single command self test
ADIS16334 or ADIS16485. The ADIS16448 is packaged in a
Single-supply operation: 3.15 V to 3.45 V
module that is approximately 24.1 mm × 37.7 mm × 10.8 mm
2000 g shock survivability
and has a standard connector interface.
