Note 12. All blocks are powered-up (PMVCM=PMADC=PMDAC=PMHPL=PMHPR=PMMO= “1”), and HP-Amp

output is off. AVDD=9mA(typ), DVDD=3mA(typ), HVDD=3mA(typ).

9mA(typ) at playback only (PMVCM=PMDAC=PMHPL=PMHPR=PMMO= “1”, PMADC= “0”).

AVDD=4mA(typ), DVDD=2mA(typ), HVDD=3mA(typ).

Note 13. All digital input pins including clock pins (MCLK, BICK and LRCK) are held at DVDD or DVSS. PDN pin is

held at DVSS.
