GENERAL DESCRIPTION
The ADIS16505 is a precision, miniature microelectomechanical
system (MEMS) inertial measurement unit (IMU) that includes
a triaxial gyroscope and a triaxial accelerometer. Each inertial
sensor in the ADIS16505 combines with signal conditioning
that optimizes dynamic performance. The factory calibration
characterizes each sensor for sensitivity, bias, alignment,
linear acceleration (gyroscope bias), and point of percussion
(accelerometer location). As a result, each sensor has dynamic
compensation formulas that provide accurate sensor
measurements over a broad set of conditions.
The ADIS16505 provides a simplified, 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 serial peripheral interface (SPI) and register
structure provide a simple interface for data collection and
configuration control.
The ADIS16505 is available in a 100-ball, ball grid array (BGA)
package that is approximately 15 mm × 15 mm × 5 mm.
