Technical note

A3G4250D: supplementary data related to the

3-axis digital output gyroscope

Introduction

The purpose of this technical note is to provide supplementary information related to the

A3G4250D gyroscope (3D digital gyroscope for automotive telematics/navigation

applications). This document explains the procedure to execute the asynchronous mode

reading of data sets based on device behavior in consumer applications.

This document does not replace the content of the A3G4205D datasheet, with the exception

of Figure 10 on page 20 in paragraph 3.2.4, which is modified as follows in the figure below.
