Figure 53. Mono Lineout Sequence
<Example>
At first, clocks should be supplied according to
“
Clock Set Up
”
sequence.
(1) Set up a sampling frequency (FS3-0 bits). When the AK4632 is PLL mode, DAC and Mono Line Amp should
be powered-up in consideration of PLL lock time after a sampling frequency is changed.
(2) Set up the path of
“
DAC
Mono Line Amp
”
DACA bit:
“
0
”
→
“
1
”
(3) Set up the digital volume (Addr: 0AH)
After DAC is powered-up, the digital volume changes from default value (0dB) to the register setting value by
the soft transition.
(4) Power Up of DAC and Mono Line Amp: PMDAC bit = PMAO bit =
“
0
”
→
“
1
”
When DAC and Mono Line Amp are powered-up, the pop noise occurs from AOUT pin. Therefore AOUT pin
should be muted by external circuit.
(5) Power Down of DAC and Mono Line Amp: PMDAC bit = PMAO bit =
“
1
”
→
“
0
”
When DAC and Mono Line Amp are powered-down, the pop noise occurs from AOUT pin. Therefore AOUT
pin should be muted by external circuit.
(6) Disable the path of
“
DAC
Mono Line Amp
”
DACA bit:
“

”
→
“
0
”
