Figure 54. 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) Enter power-save mode of Mono Line Amp: AOPSN bit =
0
1
(5) Power Up of DAC and Mono Line Amp: PMDAC bit = PMAO bit =
0
1
AOUT pin rises up to VCOM voltage. Rise time is 200ms (max 300ms) at C=1
μ
F.
(6) Exit power-save mode of Mono Line Amp after AOUT pin rises up. : AOPSN bit =
1
0
Mono Line Amp goes to normal operation.
(7) Enter power-save mode of Mono Line Amp: AOPSN bit =
0
1
(8) Power Down of DAC and Mono Line Amp: PMDAC bit = PMAO bit =
1
0
AOUT pin falls down to AVSS. Fall time is 200ms (max 300ms) at C=1
μ
F.
(9) Disable the path of
DAC
Mono Line Amp
: DACA bit:
1

(10) Exit power-save mode of Mono Line Amp after AOUT pin falls down. : AOPSN bit =
1
