AK4683 Evaluation Board Rev.1
FEATURE
AKD4683-A is an evaluation board for AK4683, a single chip 24bit CODEC that has two channels of ADC
and four channels of DAC with internal DIR, DIT. This board has interfaces with AKM’s evaluation boards
for A/D converter and D/A converter and makes easy to evaluate AK4683. Also this board has the digital
audio interface and then achieves the interface with digital audio systems via opt-connector or RCA
connector.

AKD4683-A --- AK4683 Evaluation Board
10 wire flat cable for connection with printer port of PC (IBM-AT compatible machine),
control software for AK4589, driver for control software on Windows 2000/XP are
packed with this.
Control software does not work on Windows NT
Windows 2000/XP needs an installation of driver.
Windows 95/98/ME does not need an installation of driver.
AK4683 supports the standard-mode I²C-bus (max: 100kHz), and does not support a
fast-mode I²C-bus system (max: 400kHz).
