Figure 5. Load Capacitance C_L2 and C_L3 (Using Sag Compensation circuit)
Note 21.PLL Master Mode (MCKI = 12MHz) and PMMP = PMADC = PMDAC = PMPFIL = PMSPK = PMVCM =
PMPLL = MCKO = PMAO = M/S = “1” and PMV bit = “0”. And output current from the MPI pin is 0mA.
When the AK4635 is EXT mode (PMPLL = MCKO = M/S = “0”), “AVDD+DVDD” is typically TBD
mA@fs=8kHz, TBDmA@fs=48kHz
Note 22. PMVCM = PMV bits = “1”, PMMP = PMADC = PMDAC = PMPFIL = PMSPK = PMPLL = MCKO = PMAO
= M/S =“0”. And output current from the MPI pin is 0mA. (When SAGC bit = “0”, no resistance and no input
signal of the VIN pin )
Note 23. PLL Master Mode (MCKI = 12MHz) and PMMP = PMADC = PMDAC = PMPFIL = PMSPK = PMVCM =
PMPLL = MCKO = PMAO = PMBP = M/S = PMV = “1”. And output current from the MPI pin is 0mA. (This
is the case of when SAGC bit = “0” and no load resistance and capacitance and no input signal of the VIN pin )
Note 24. When SAGC bit = “1” and Black signal is output, this current is typ.TBD mA. In the case of DC Output, this
current increases by DC voltage /150 Ω. DC Output Voltage is 0V at PMV bit = “0”, and then DC current does
not flow. When any signal is not input at using Sag Compensation Circuit, PMV bit should be set “0”.
Note 25. All digital inputs pins are fixed to DVDD or VSS2.
