The ADIS16405 iSensor® is a complete inertial system that includes
a tri-axis gyroscope, a tri-axis accelerometer, and a tri-axis mag-
netometer. The ADIS16405 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 (gyroscope
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 magnetometers
employ a self-correction function to provide accurate bias
performance over temperature as well.
The ADIS16405 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 produc-
tion 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 and ADIS1636x families, upgrading to the ADIS16405
requires only firmware changes to accommodate additional sensors
and register map updates.
This compact module is approximately 23 mm × 23 mm × 23 mm
and provides a flexible connector interface, which enables multiple
mounting orientation options.
