AKD4341-SB
AK4341 Evaluation Board Rev.0
General Description AKD4341-SB is an evaluation board for AK4341 (192kHz sampling 24Bit DAC). AKD4341-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 AK4341. Ordering Guide AKD4341-SB ---- AK4341 Evaluation Board Function On-board digital audio interface. (AK4113)

Operation sequence
1) Set up the power supply lines. (See "Other jumpers set-up".) Name of jack +9V (J4) +5V (J5) +3.3V (J6) GND (J7) GND (J8) Color of jack Red Red Red Black Black Voltage +12+15V +4.5+5.5V +2.7+3.6V 0V 0V Used for HVDD of AK4341, Regulator T1 TVDD of AK4113, Logic circuit AVDD and DVDD of AK4341, Logic circuit GND GND Comments and attention This jack should be always connected to power supply. This jack should be always connected to power supply. This jack should be always connected to power supply. This jack should be always connected to power supply. This jack is used when the ground is separated. Please set 0 jumper of R28 from R31 properly. Default setting +9V +5V +3.3V 0V open
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.
JP3 OPT COAX (COAX) (Default)
