AKD4340-SB
AK4340 Evaluation Board Rev.0
General Description
AKD4340-SB is an evaluation board for AK4340 (192kHz sampling 24Bit ∆Σ DAC). AKD4340-SB has a
digital audio interface (AK4113) of Optical or COAX input and can easily achieve the interface with digital
audio system. Therefore, it is easy to evaluate the sound quality of AK4340.

„ Evaluation mode
1. Using DIR (COAX) (default)
It is possible to evaluate the AK4340 by using CD disk. The DIR generates MCLK, BICK, LRCK and SDATA from the
received data through BNC connector (J1). Setting of jumper is shown below.
COAX is recommended for an evaluation of the Sound quality.

Control Software Manual
„ Set-up of evaluation board and control software
1. Set up the AKD4340-SB according to previous term.
2. Connect IBM-AT compatible PC with AKD4340-SB by 10-line type flat cable (packed with AKD4340-SB). Take
care of the direction of 10pin header. (Please install the driver in the CD-ROM when this control software is used
on Windows 2000/XP. Please refer “Installation Manual of Control Software Driver by AKM device control
software”. In case of Windows95/98/ME, this installation is not needed. This control software does not operate on
Windows NT.)
