GENERAL DESCRIPTION
The ADIS16477 is a precision, miniature MEMS inertial measure-
ment unit (IMU) that includes a triaxial gyroscope and a triaxial
accelerometer. Each inertial sensor in the ADIS16477 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 ADIS16477 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 serial peripheral interface (SPI) and register
structure provide a simple interface for data collection and
configuration control.
The ADIS16477 is available in a 44-ball, ball grid array (BGA)
package that is approximately 11 mm × 15 mm × 11 mm.
