The ADIS16488A 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
ADIS16488A 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 ADIS16488A 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 ADIS16488A uses the same footprint and connector system as
the ADIS16375, ADIS16480, and ADIS16485, which greatly
simplifies the upgrade process. The ADIS16488A is packaged in
a module that is approximately 47 mm × 44 mm × 14 mm and
includes a standard connector interface.
