GENERAL DESCRIPTION

The ADIS16488 iSensor® device is a complete inertial system

that includes a triaxis gyroscope, a triaxis accelerometer, triaxis

magnetometer, and pressure sensor. Each inertial sensor in the

ADIS16488 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 ADIS16488 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 ADIS16488 uses the same footprint and connector system as

the ADIS16375, which greatly simplifies the upgrade process. It

comes in a module that is approximately 47 mm × 44 mm ×

14 mm and has a standard connector interface.
