GENERAL DESCRIPTION
AKD4366 is an evaluation board for 24bit DAC with built-in Headphone Amplifier, AK4366. The
AKD4366 has the interface with AKM's ADC evaluation boards. Therefore, it's easy to evaluate the
AK4366. The AKD4366 also has the digital audio interface and can achieve the interface with digital
audio systems via opt-connector.

Operation sequence
1) Set up the power supply lines.
[+5V] (red) = 5V
[AGND] (black) = 0V : for analog ground
[DGND] (black) = 0V : for logic ground
Each supply line should be distributed from the power supply unit.
2) Set up the evaluation mode, jumper pins.
(See the followings.)
3) Power on.
The AK4366 and AK4116 should be resets once bringing SW1 (DAC_PDN) and SW2 (DIR_PDN) "L" upon
power-up.
n
Evaluation mode
Applicable Evaluation Mode
(1) In case of using DIR (Optical Link) <default>
(2) In case of connecting AK4366 with a external DSP
(1) In case of using DIR (Optical Link) <default>
PORT1 (DIR) is used. DIR generates MCLK, BICK, LRCK and SDATA from the received data through optical
connector (TORX141). Nothing should be connected to PORT3 (DSP).

The function of the toggle SW
Upper-side is "H" and lower-side is "L".
[SW1] (DAC_PDN) : Resets the AK4366. Keep "H" during normal operation.
[SW2] (DIR_PDN) : Resets the AK4116. Keep "H" during normal operation.
n
Indication for LED
[LED1] (ERF): Monitor INT0 pin of the AK4116. LED turns on when unlock or parity error occurs.
n
Serial Control
The AK4366 can be controlled via the printer port (parallel port) of IBM-AT compatible PC. Connect PORT2
(uP-I/F) with PC by 10 wire flat cable packed with the AKD4366.
