GENERAL DESCRIPTION

The ADIS16575/ADIS16576/ADIS16577 are a precision, microelec-

tromechanical system (MEMS) inertial measurement unit (IMU) that

includes a triaxial gyroscope and a triaxial accelerometer. Each

inertial sensor in the ADIS16575/ADIS16576/ADIS16577 integrates

signal conditioning to optimize dynamic performance. The factory

calibration characterizes each sensor for sensitivity, bias, and align-

ment. Therefore, each sensor has dynamic compensation formulas

that provide accurate sensor measurements over a broad set of

conditions.

The ADIS16575/ADIS16576/ADIS16577 provide a simple, cost ef-

fective method for integrating accurate, multiaxis inertial sensing

into industrial systems, especially when compared to the complexity

and investment associated with discrete designs. All necessary mo-

tion 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 serial peripheral interface (SPI) and register structure provide a

simple interface for data collection and configuration control.

The ADIS16575/ADIS16576/ADIS16577 are in an aluminum mod-

ule package that is approximately 24.30 mm × 22.40 mm × 13.70

mm with a 14-lead connector interface.
