Regulatory Compliance
The Audio EI3 Extender Board is designed to be used solely in a labora-
tory environment. The board is not intended for use as a consumer end
product or as a portion of a consumer end product. The board is an open
system design which does not include a shielded enclosure and therefore
may cause interference to other electrical devices in close proximity. This
board should not be used in or near any medical equipment or RF devices.
The Audio EI3 Extender Board is in the process of being certified to com-
ply with the essential requirements of the European EMC directive
89/336/EEC (inclusive 93/68/EEC) and, therefore, carries the “CE”
mark.
The extender board contains ESD (electrostatic discharge) sensitive devices.
Electrostatic charges readily accumulate on the human body and equipment
and can discharge without detection. Permanent damage may occur on
devices subjected to high-energy discharges. Proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
Store unused extender boards in the protective shipping package.

Audio EI3 Extender Board Manual vii
PREFACE
Thank you for purchasing the Audio EI3 Extender Board, an
EZ-Extender®product for EZ-KIT Lite®/EZ-Board®evaluation systems.
The EZ-KIT Lite/EZ-Board and Audio EI3 Extender Board are designed
to be used in conjunction with the CrossCore®Embedded Studio devel-
opment environment. CrossCore Embedded Studio (CCES) offers a
powerful programming tool with new flexibility that significantly
decreases the time required to port software code to a processor, reducing
time-to-market.
To learn more about Analog Devices development software, go to
http://www.analog.com/processors/tools.
Product Overview
The Audio EI3 Extender Board is a separately sold daughter board that
plugs onto the expansion interface (EI3) of an EZ-KIT Lite/EZ-Board
evaluation system. The extender board aids the design and prototyping
phases of the embedded processor-targeted applications. For more infor-
mation refer to the product website, http://www.analog.com/EI3-Audio.
The Audio EI3 Extender Board utilizes the ADAU1761 SigmaDSP®
stereo, low power, 96 kHz, 24-bit audio codec. The codec provides line
input, line output, auxiliary input and headphone output.
