Note 11. Maximum Input Voltage is proportional to AVDD voltage. Vin = 0.6 x AVDD(typ).
Note 12. When ALC2 Gain is changed, this typical value changes between 22k
and 26k
.
Note 13. Output Voltage is proportional to AVDD voltage. Vout = 0.588 x AVDD(typ).
Note 14. When the output pin drives a capacitive load, a resistor should be added in series between the output pin and
capacitive load.
Note 15. Maximum Input Voltage is proportional to AVDD voltage. Vin = 0.6 x AVDD(typ).
Note 16. PMMIC=PMADC=PMDAC=PMMO=PMSPK=PMHPL=PMHPR=PMVCM=PMPLL=PMXTL=PMBPM=
PMBPS=PMAUX= “1”, MCKO= “1” and Master Mode. AVDD=10mA (typ.), DVDD=6mA (typ.).
AVDD=10mA (typ.), DVDD=4mA (typ.) at MCKO= “0” in Slave Mode.
Note 17. PMMIC=PMADC=PMDAC=PMMO=PMHPL=PMHPR=PMVCM=PMPLL= PMXTL=PMBPM=PMBPS=
PMAUX= “1” and PMSPK= “0”.
Note 18. PMMIC=PMADC=PMDAC=PMMO=PMSPK=PMVCM=PMPLL=PMXTL= PMBPM=PMBPS=PMAUX=
“1” and PMHPL=PMHPR= “0”.
Note 19. All digital input pins are fixed to DVDD or DVSS. When the voltage difference among DVDD, PVDD and
AVDD is larger than 0.3V, the power supply current at power down mode increases.
