Compact, Precision Six Degrees of Freedom Inertial Sensor Data Sheet ADIS16445 FEATURES GENERAL DESCRIPTION Triaxial digital gyroscope with digital range scaling
The ADIS16445 iSensor® device is a complete inertial system
±62°/sec, ±125°/sec, ±250°/sec settings
that includes a triaxial gyroscope and a triaxial accelerometer.
Axis-to-axis alignment, <0.05°
Each sensor in the ADIS16445 combines industry-leading
Triaxial digital accelerometer, ±5 g minimum
iMEMS® technology with signal conditioning that optimizes
Autonomous operation and data collection
dynamic performance. The factory calibration characterizes
No external configuration commands required
each sensor for sensitivity, bias, and alignment. As a result, each
175 ms start-up time
sensor has its own dynamic compensation formulas that provide
Factory calibrated sensitivity, bias, and axial alignment
accurate sensor measurements.
Calibration temperature range: −40°C to +85°C
The ADIS16445 provides a simple, cost-effective method for
SPI-compatible serial interface
integrating accurate, multiaxis inertial sensing into industrial
Embedded temperature sensor
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 the

factory, greatly reducing system integration time. Tight orthogonal
Digital I/O: data ready, alarm indicator, general-purpose
alignment simplifies inertial frame alignment in navigation systems.
Alarms for condition monitoring
The SPI and register structures provide a simple interface for

data collection and configuration control.
Single command self-test Single-supply operation: 3.15 V to 3.45 V
The ADIS16445 has a compatible pinout for systems that cur-
