GENERAL DESCRIPTION

The ADIS16362 iSensor® is a complete inertial system that includes

a triaxis gyroscope and triaxis accelerometer. Each sensor in the

ADIS16362 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 over a temperature

range of −20°C to +70°C.

The ADIS16362 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. An improved SPI interface and register

structure provide faster data collection and configuration control.

The ADIS16362 uses 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.

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

and provides a flexible connector interface that enables multiple

mounting orientation options.
