GENERAL DESCRIPTION
The ADIS16364 iSensor® is a complete inertial system that
includes a tri-axis gyroscope and tri-axis accelerometer. Each
sensor in the ADIS16364 combines industry-leading iMEMS®
technology with signal conditioning that optimizes dynamic
performance.
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. An improved SPI
interface and register structure provide faster data collection and
configuration control. By using a compatible pinout and the
same package as the ADIS1635x family, systems that currently
use the ADIS1635x family can upgrade their performance with
minor firmware changes to accommodate scale factor
adjustments.
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 for correction
formulas that provide accurate sensor measurements over a
temperature range of −40°C to +85°C.
This compact module is approximately 23 mm × 23 mm × 23
mm and provides a flexible connector interface, which enables
multiple mounting orientation options.
The ADIS16364 provides a simple, cost-effective method for
integrating accurate, multi-axis, inertial sensing into industrial
systems, especially when compared with the complexity and
investment associated with discrete designs.
