GENERAL DESCRIPTION
The ADIS16407 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 ADIS16407 combines industry-leading iMEMS® technology
with signal conditioning that optimizes dynamic performance.
The factory calibration characterizes each sensor for sensitivity,
bias, alignment, and linear acceleration (gyro bias). As a result,
each sensor has its own dynamic compensation formulas that
provide accurate sensor measurements.
The ADIS16407 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 structure provide a simple interface for
data collection and configuration control.
The ADIS16407 has a compatible pinout for systems that currently
use ADIS1635x, ADIS1636x, and ADIS1640x IMU products.
The ADIS16407 is packaged in a module that is approximately
23 mm × 23 mm × 23 mm and has a standard connector interface.
