GENERAL DESCRIPTION

The ADIS16360/ADIS16365 iSensor® devices are complete inertial
systems that include a triaxis gyroscope and triaxis accelerometer.
Each sensor in the ADIS16360/ADIS16365 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 ADIS16360/ADIS16365 provide 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 naviga-
tion systems. An improved SPI interface and register structure
provide faster data collection and configuration control.
The ADIS16360/ADIS16365 use a compatible pinout and the same
package as the ADIS1635x family. Therefore, systems that currently
use the ADIS1635x family can upgrade their performance with
minor firmware adjustments in their processor designs. These
compact modules are approximately 23 mm × 23 mm × 23 mm
and provide a flexible connector interface that enables multiple
mounting orientation options.
