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.

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.

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.

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.

This compact module is approximately 23 mm × 23 mm × 23

mm and provides a flexible connector interface, which enables

multiple mounting orientation options.
