General Description
AKD4341-SB is an evaluation board for AK4341 (192kHz sampling 24Bit ΔΣ DAC). AKD4341-SB has a
digital audio interface (AK4113) of Optical or COAX input and can easily achieve the interface with digital
audio system. Theref ore, it is easy t o evaluate the soun d quality of AK4341.

Table 1. Set up of power supply lines
Each supply line should be distributed from the power supply unit.
2) Set-up the jumper pins
3) Set-up the DIP switches. (See the followings.)
4) Power on
The AK4341 should be reset once by bringing SW3 (PDN) “L” upon power-up.

Evaluation mode
1. Using DIR (COAX) (default)
It is possible to evaluate the AK4341 by using CD disk. The DIR generates MCLK, BICK, LRCK and SDATA from the
received data through BNC connector (J3). Setting of jumper is shown below.
COAX is recommended for an evaluation of the Sound quality.
