GENERAL DESCRIPTION
The ADIS16400/ADIS16405 iSensor® products are complete
inertial systems that include a triaxal gyroscope, a triaxial
accelerometer, and a triaxial magnetometer. The ADIS16400/
ADIS16405 combine 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 ADIS16400/ADIS16405 provide a simple, cost-effective
method for integrating accurate, multi-axis inertial sensing into
industrial systems, especially when compared with the
Rev. B

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 serial peripheral interface
(SPI) 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 ADIS16400/ADIS16405 requires only firmware
changes to accommodate additional sensors and register map
updates.
These compact modules are approximately 23 mm × 23 mm ×
23 mm and provide a flexible connector interface that enables
multiple mounting orientation options.
