External analog circuit
J1(AOUTL) and J2(AOUTR) are used. The analog output signal range is nominally 3.1Vpp@5V. It is proportional
to AVDD (Vout=0.62xAVDD).

Operation sequence
1) Set up the power supply lines.

: for logic ground
Each supply line should be distributed from the power supply unit.
2) Set up the evaluation mode, jumper pins and DIP switches.
(See the followings.)
3) Power on.
The AK4364 should be reset once bringing SW1(-PD) “L” upon power-up.
4) Connect PORT2 with PC.
Connect PORT2 with printer port (parallel port) of IBM-AT compatible PC by 10-line flat cable packed with
the AKD4364. Take care of the direction of connector. There is a mark at 1pin. The direction of PORT2 is as
the following figure.

5) Set up the software.
Use the software named “AKD4364 Control Program” packed with the AKD4364.

Evaluation mode
1) Using A/D converted data <default>
PORT3 (ADC/ROM) is used to interface with various AKM’s A/D converter evaluation boards. In case of
using external clock through a BNC connector (J4), select BNC on JP14 (CLK) and short JP15 (XTE).
