GENERAL DESCRIPTION All necessary motion testing and calibration are part of the The ADIS16405 iSensor product is a complete inertial system that includes a triaxal gyroscope, a triaxial accelerometer, and a production process at the factory, greatly reducing system triaxial magnetometer. The ADIS16405 combines the Analog integration time. Tight orthogonal alignment simplifies inertial Devices, Inc., proprietary iMEMS technology with signal frame alignment in navigation systems. An improved serial conditioning that optimizes dynamic performance. The factory peripheral interface (SPI) and register structure provide faster calibration characterizes each sensor for sensitivity, bias, data collection and configuration control. By using a compatible alignment, and linear acceleration (gyroscope bias). As a result, pinout and the same package as the ADIS16362/ADIS16364/ each sensor has its own dynamic compensation for correction ADIS16365 family, upgrading to the ADIS16405 requires only firmware changes to accommodate additional sensors and register formulas that provide accurate sensor measurements over a temperature range of 40C to +85C. The magnetometers map updates. employ a self correction function to provide accurate bias This compact module is approximately 23 mm 23 mm 23 mm performance over temperature as well. and provides a flexible connector interface that enables multiple The ADIS16405 provides a simple, cost effective method for mounting orientation options. integrating accurate, multiple axis inertial sensing into industrial systems, especially when compared with the complexity and investment associated with discrete designs.
