(max: GN4-0 bits = “00H”)
(min: GN4-0 bits = “1FH”)
Power Supplies:
Power Up (RESETN pin = “H”)
All Circuit Power-up:
AVDD+DVDD (Note 25)
HVDD: HP-AMP Normal Operation
No Output (Note 26)
HVDD: SPK-AMP Normal Operation
No Output (Note 27)
Power Down (RESETN pin = “L”) (Note 28)
AVDD+DVDD+HVDD
Note 23. Maximum Input Voltage is proportional to AVDD voltage. Vin = 0.6 x AVDD(typ).
Note 24. Maximum Input Voltage is proportional to AVDD voltage. Vin = (AUXIN+)
(AUXIN
) = 0.6 x AVDD(typ).
Note 25. PR0-6 bits = all “0”, PMMIC=PMMO=PMSPK=PMHPL=PMHPR=PMBPM=PMAUX=PMLIN= “1”.
AVDD=10mA (typ.), DVDD=5mA (typ.).
Note 26. PR0-6 bits = all “0”, PMMIC=PMMO=PMHPL=PMHPR=PMBPM=PMAUX=PMLIN= “1”, PMSPK= “0”.
Note 27. PR0-6 bits = all “0”, PMMIC=PMMO=PMSPK=PMBPM=PMAUX=PMLIN= “1”, PMHPL=PMHPR= “0”.
Note 28. All digital input pins are fixed to DVDD or DVSS. When the voltage difference among AVDD, DVDD and
HVDD is larger than 0.3V, the power supply current at power down mode increases.
