Note 31. When PMVCM = PMMPA = PMMPB = PMAD0 = PMAD1 = PMAD2 = PMAD3 = PMDACA = PMDACB =
PMLO = PMHPL = PMHPR = PMSPLO = PMBP = PMDSP = PMPFIL0 = PMPFIL1 = PMPFIL2 = PMPFIL3
= PMDRC bits = “1”. There is no input to MICIN0L/DDAT0, MICIN0R/DMCLK, MICIN1L/DDAT1,
MICIN1R, MICIN2L, MICIN2R, MICIN3L, MICIN3R, AUXINL, AUXINR and BEEPIN pins. The SDTI pin
input is 1kHz and 0dBFS. No load to the LOUTA/ROUTA, SPP/SPN and HPL/HPR pins. Path settings are
PFSEL =DRCENA=DRCENB=BEEPS bits= “0”, PFSDO bit= “1”, DASEL1-0 bits = “00” and DACS bit = “1”.
In this case, the MPWRA and MPWRB pins output 0mA.
AVDD= 17.7mA (typ), DVDD= 4.0mA(typ), TVDD= 0.1mA (typ), SVDD= 2.1mA (typ).
Note 32. All digital input pins are fixed to TVDD or VSS2.
■ Power Consumption on Each Operation Mode
Conditions: Ta=25C; AVDD= SVDD=TVDD=2.8V, DVDD=1.8V; VSS1=VSS2=VSS3= 0V; fs=48kHz, External Slave
Mode, BCKI=64fs; 1kHz, 0dBFS input; MPWRA/B & Headphone & Speaker & Line output = No load.
