2-1) D/A Evaluation using the AK4118A (DIR) (Coaxial connectior) < default >
The AK4118A generates MCLK, BICK, LRCK, SDATA1 and SDATA2 from the data from the BNC
connector (J1). Evalutations using a test CD and etc. are available(Note 3).
Setting: R46 = “open”, R48 = “short (0Ω)”
Note 3. Coaxial connection is recommended when evaluating the sound quality.
2-2) D/A Evaluation using the AK4118 (DIR) (Optical connectior)

4) Power ON
Switch Up: “ON (H)”. Switch Down: “OFF (L)”.
Power-down reset by SW1(PDN) and SW2(DIR-PDN) must be made once after power up the evaluation
board. Put the SW1 and SW2 to “L” for power-down reset of the AK4414 and AK4118A, and the return them
to “H” to release the power-down states.
[SW1] (PDN): Resets the AK4414 (Keep “H” during normal operation.)
This switch must be set to “L” once upon power up the evaluation board to reset the AK4414.
[SW2] (DIR-PDN): Resets the AK4118A (Keep “H” during normal operation.)
This switch must be set to “L” once upon power up the evaluation board to reset the
AK4118A. When not using the AK4118A, keep this switch to “L”.

■ Board Control
The AKD4414-SA can be controlled via a USB port with a PC. Connect J2 (USB) connector to a PC with USB
cable. The control software is included in the AK4413-SA package. Refer to the “Control Software Manual”
paragraph for operational sequence of the control software.
■ External Analog Filter
The AKD4414 has a differential output circuit that outputs differential outputs of the AK4414 via a non-inverting
buffer (second order LPF, fs=106.4k, Q=0.698, G=+3.9dB) and a LPF (first order LPF, fs=284k, G=-0.84dB). A
low-noise and high-voltage operatinal amplifier the LME49710NA is used on the AKD4414. The output signal
from the BNC connector is about 2.8Vrms (Typ@VREF=5.0V).

■ Capacitor between VREFH and VREFL pins
Low-frequency distortion can be improved by connecting a large capacitance capacitor between the VREFH pin
and the VREFL pin. (Figure 3) Capacitors between the VREFH pin and the VREFL pin are shown as C159 and
C160 in the circuit diagram.

■ Tab Descriptions
1. [REG]: Register Map
This tab is for register read and write.
Each bit on the register map is a push-button switch.
Button Down indicates “1” and the bit name is shown in red (when read-only, the name is shown in dark red).
Button Up indicates “0” and the bit name is shown in blue (when read-only, the name is shown in gray)
Grayed out registers are read-only registers. They can not be controlled.
The registers which are not defined on the datasheet are indicated as “---”.
