GENERAL DESCRIPTION
The ADIS16485 iSensor® device is a complete inertial system that
includes a triaxial gyroscope and a triaxial accelerometer. Each
inertial sensor in the ADIS16485 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 formulas that provide accurate sensor measurements.
The ADIS16485 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.
The SPI and register structure provide a simple interface for
data collection and configuration control.
The ADIS16485 uses the same footprint and connector system
as the ADIS16375 and ADIS16488, which greatly simplifies the
upgrade process. It comes in a module that is approximately 47 mm
www.DataSheet.co.kr × 44 mm × 14 mm and has a standard connector interface.
