= 5V
= open (3.0V, supply from regulator, for AVDD of AK5702)
= open (3.0V, supply from regulator, for DVDD of AK5702)
= 2.7 ∼ 3.6V (typ. 3.0V, for logic of digital part)
= 0V (for analog ground)
= 0V (for digital ground)
1-2) When AVDD, DVDD and VD are not supplied from the regulator.

= 2.4 ∼ 3.6V (typ. 3.0V, for AVDD of AK5702)
= 1.6 ∼ 3.6V (typ. 3.0V, for DVDD of AK5702)
= 2.7 ∼ 3.6V (typ.3.0V, for logic of digital part)
= 0V (for analog ground)
= 0V (for digital 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 AK5702 and AK4114 should be reset once by bringing SW1, 2 “L” upon power-up.
„ Evaluation mode
In case of AK5702 evaluation using AK4114, same audio interface format should be set for both AK5702 and
AK4114. About AK5702’s audio interface format, refer to datasheet of AK5702. About AK4114’s audio
interface format, refer to Table 2 in this manual.
Applicable Evaluation Mode
(1) PLL Master Mode (Default)
(2) PLL Slave Mode 1 (PLL Reference CLOCK: MCKI pin)
(3) PLL Slave Mode 2 (PLL Reference CLOCK: BCLK or LRCK pin)
(4) EXT Slave Mode
(5) EXT Master Mode
