(Black)
= 0V
2) Set up the jumper pins. (Refer the next section.)
They should be set a default state.
3) Turn on the power supply.
AK4252VU includes a power-on-reset function. Therefore any reset is not required upon power-up externally.
„ Jumper pins set up
Jumper pins should be set the default state.
1) JP1 (DVDD) : DVDD and AVDD
