ADAV4601 System Design Document Confidential Information
Rev.1 August 2009 Analog Devices Page 5
INTRODUCTION
The purpose of this document is to help with the design in of the ADAV4601 into a system. The document is
detailed as follows
•
Section 1 – Getting the Evaluation Board Up and Running
Outlines the ADAV4601 evaluation board. Gives a brief description of the ways in which the evaluation
board and the ADAV4601 can be configured. This evaluation board can be used as a template for the
design of the ADAV4601 into a system.
•
Section 2 – Powering up the ADAV4601
Details a specially designed power up sequence for the ADAV4601 which allows the part to be powered
up and down with no pops or clicks. This power up sequence should be used when the ADAV4601 has
been designed into a system.
•
Section 3 – Programming the ADAV4601
Details the ways in which the ADAV4601 can be programmed and controlled. This section details how the
user can control the default audio flow on the ADAV4601 or create a new audio flow from scratch
SigmaStudio.
•
Section 4 – The Default Flow
•
Section 5 – Interfacing the ADAV4601 to a System
•
Section 6 – The Application Layer Creation Software
Only used if the user decides to create their own customized audio flow. The Application Layer allows the
user to define their own register map for the audio flow they have created in SigmaStudio; in which they
can define controls for filter cut-offs, volumes, third party algorithms etc.
