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”.
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
MS0503-E-00
All Circuit Power-up:
AVDD+DVDD+HVDD
AVDD=10mA (typ.), DVDD=5mA (typ.).
HVDD is larger than 0.3V, the power supply current at power down mode increases.
AVDD+DVDD (Note 25)
HVDD: HP-AMP Normal Operation
HVDD: SPK-AMP Normal Operation
