Note 18. The maximum value is AVDD Vpp when BPVCM bit = “1”. However, a click noise may occur when
the amplitude after BEEP-Amp is 0.5Vpp or more. (set by BPLVL3-0 bits)
Note 19. The gain is in inverse proportion to external input resistance.
Note 20. When PLL Master Mode (MCKI=12MHz), and PMADL=PMADR=PMDAC=PMPFIL=PMHPL=
PMHPR= PMVCM=PMPLL =PMBP=PMMP=M/S bits = “1”. In this case, the MPWR1 (MPWR2)
pin outputs 0mA. AVDD= 4.4mA (typ), DVDD= 2.0mA (typ), TVDD= 0.08mA (typ).
Note 21. When EXT Slave Mode (PMPLL=M/S bits =“0”),
PMADL=PMADR=PMDAC=PMHPL=PMHPR= PMVCM=PMBP=PMMP bits = “1”, and
PMPFIL bit = “0”. In this case, the MPWR1 (MPWR2) pin outputs 0mA. AVDD= 4.2mA (typ),
DVDD= 1.5mA (typ), TVDD= 0.02mA (typ).
Note 22. When PLL Master Mode (MCKI=12MHz), and PMADL=PMADR=PMDAC=PMPFIL=PMSL=
PMVCM= PMPLL =PMBP=PMMP=SLPSN=DACS=M/S bits = “1”. In this case, the MPWR1
(MPWR2) pin outputs 0mA. AVDD= 3.8mA (AK4951EN: typ), 5.6mA (AK4951EG: typ), DVDD=
1.7mA (typ), TVDD= 0.08mA (typ).
Note 23. When EXT Slave Mode (PMPLL=M/S bits =“0”), PMADL=PMADR=PMDAC=PMSL=PMVCM=
PMBP=PMMP=SLPSN=DACS bits = “1”, and PMPFIL bit = “0”. In this case, the MPWR1
(MPWR2) pin outputs 0mA. AVDD= 3.5mA (AK4951EN: typ), 5.3mA (AK4951EG: typ), DVDD=
1.2mA (typ), TVDD= 0.02mA (typ).
Note 24. All digital input pins are fixed to TVDD or VSS2.
Note 25. When AVDD, DVDD and TVDD are powered OFF.
