[REG] (red)
= 5.0V
: for regulator (3.3V output : HVDD, AVDD, TVDD1, TVDD2,
TSVDD, DVDD of AK4673)
[D3V] (orange) = 2.7 ∼ 3.6V : for AK4114 and logic (typ. 3.3V)
[AGND] (black) = 0V
: for analog ground
[DGND] (black) = 0V
: for logic ground
(1-2) In case of using the power supply connectors.
Set up the jumper pins.

Set up the power supply lines.
[HVDD] (orange) = 1.6 ~ 3.6V : for HVDD of AK4673 (typ. 3.3V)
[AVDD] (orange) = 1.6 ~ 3.6V : for AVDD and PVDD of AK4673 (typ. 3.3V)
[DVDD] (orange) = 1.6 ~ 3.6V : for DVDD of AK4673 (typ. 3.3V)
[TVDD] (orange) = 1.6 ~ 3.6V : for TVDD1, TVDD2, TSVDD of AK4673 (typ. 3.3V)
[VCC] (orange) = 1.6 ∼ 3.6V : for logic (typ. 3.3V: = DVDD)
[D3V] (orange) = 2.7 ∼ 3.6V : for AK4114 and logic (typ. 3.3V)
[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 and DIP switches. (See the followings.)
(3) Power on.
The AK4673 and AK4114 should be resets once bringing SW1 (PDN) and SW2 (DIR) “L” upon power-up.
