Note 11. All blocks are powered-up (MVCM=PMADC=PMDAC=PMHPL=PMHPR=PMLO=PMCP=PMMP bits =
“1”), and HP-AMP output is off. Output current of MPWR pin is 0mA.
AVDD=12mA(typ), DVDD+TVDD=2mA(typ), HVDD=6mA(typ).
14mA(typ) at playback only (PMVCM=PMDAC=PMHPL=PMHPR=PMLO=PMCP bits = “1”, PMADC bit
= “0”), AVDD=6.5mA(typ), DVDD+TVDD=1.5mA(typ), HVDD=6mA(typ).
Note 12. All digital input pins including clock pins (MCLK, BICK and LRCK) are held at DVDD or DVSS. PDN pin is
held at DVSS.
