GENERAL DESCRIPTION

The ADIS16545/ADIS16547 are a complete inertial system that includes

a triaxis gyroscope and a triaxis accelerometer. Each inertial

sensor in the ADIS16545/ADIS16547 combines with signal conditioning

that optimizes dynamic performance. The factory calibration

characterizes each sensor for sensitivity, bias, and alignment. As

a result, each sensor has its own dynamic compensation formulas

that provide accurate sensor measurements.

The ADIS16545/ADIS16547 provide 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

and precision alignment features simplify 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 footprint and connector system of the ADIS16545/ADIS16547

enable a simple upgrade from the ADIS16488A, ADIS16495 and

ADIS16497. Note, however, that there is a small difference in sample

rate between the ADIS16495 and the ADIS16545/ADIS16547

if the internal oscillator is used. The same small difference in

sample rate exists between the ADIS16497 and the ADIS16545/

ADIS16547. Refer to the Specifications section for details about the

native sample rate. The ADIS16545/ADIS16547 are available in an

aluminum package that is approximately 47 mm × 44 mm × 14 mm

and includes a standard connector interface.
