VIN
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”.
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
= 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 )
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 )
