[5V] (red)
= 5.0V
: for LVDD of AK4691 (typ. 5.0V)
for regulator (3.0V output : SVDD, MVDD, AVDD, DVDD,
TVDD1 and TVDD2 of AK4691 and logic)
[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.
[5V] (red)
= 2.6 ~ 5.5V : for LVDD of AK4691 (typ. 3.0V)
[SVDD] (orange) = 2.6 ~ 3.6V : for SVDD of AK4691 (typ. 3.0V)
[MVDD] (orange) = 2.6 ~ 5.5V : for MVDD of AK4691 (typ. 3.0V)
[AVDD] (orange) = 2.6 ~ 3.6V : for AVDD of AK4691 (typ. 3.0V)
[DVDD] (orange) = 2.6 ~ 3.6V : for DVDD of AK4691 (typ. 3.0V)
[TVDD] (orange) = 1.6 ~ 3.6V : for TVDD1, TVDD2 of AK4691 (typ. 3.0V)
[VCC] (orange) = 1.6 ∼ 3.6V : for logic (typ. 3.0V: This voltage must be same as TVDD.)
[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 switch. (See the followings.)
(3) Power on.
The AK4691 and AK4114 should be resets once bringing SW1 (PDN) and SW2 (DIR) “L” upon power-up.
