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.
