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.
