Note 25. PLL Master Mode (MCKI=12.288MHz) and PMV=PMMIC = PMADC = PMDAC = PMSPK = PMVCM =
PMPLL = MCKO = PMAO = PMBP = MPWR = M/S =
“
1
”
. And output current from MPI pin is 0mA. When the
AK4632 is EXT mode (PMPLL = MCKO = M/S =
“
0
”
),
“
AVDD+DVDD
”
is typically 7mA@fs=8kHz,
9.5mA@fs=48kHz).
Note 26. This is the case of SAGC bits =
“
00
”
and no load resistance and capacitance. When SAGC bits =
“
10
”
and Black
signal is output, this current is typ.8mA. In the case of DC Output, this current increases by DC voltage / 150
.
DC Output Voltage is 0V at PMV bit =
“
0
”
, and then DC current doesn’t flow. When any signal isn’t input at
using Sag Compensation Circuit, PMV bit should be set to
“
0
”
.
Note 27. MCKI pin is fixed to DVSS and all digital inputs pins except MCKI pin are fixed to DVSS or DVSS.

Note 28. The passband and stopband frequencies are proportional to fs (system sampling rate).
For example, ADC is PB=0.45*fs (@-1.1dB). A reference of frequency response is 1kHz.
Note 29. The calculated delay time caused by digital filtering. This time is from the input of analog signal to setting of the
16-bit data of a channel from the input register to the output register of the ADC. This time includes the group
delay of the HPF. For the DAC, this time is from setting the 16-bit data of a channel from the input register to the
output of analog signal.
