GENERAL DESCRIPTION
The ADIS16334 iSensor® is a complete inertial system that includes
a triaxis gyroscope and triaxis accelerometer. Each sensor in the
ADIS16334 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 (gyro bias). As a result,
each sensor has its own dynamic compensation formulas that
provide accurate sensor measurements over a temperature
range of −20°C to +70°C.
The ADIS16334 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.
An improved SPI interface and register structure provide faster
data collection and configuration control.
This compact module is approximately 22 mm × 33 mm × 11 mm
and provides a compact connector interface.
