Figure 77. Speaker-Amp Output 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 AK4648 is PLL mode, DAC and Speaker-Amp should be
powered-up in consideration of PLL lock time after a sampling frequency is changed.
(2)
Set up the path of “DAC
SPK-Amp”: DACS bit = “0”
“1”
(3)
SPK-Amp gain setting: SPKG2-0 bits = “000”
“001”
(4)
Set up Timer Select for ALC (Addr: 06H)
(5)
Set up REF value for ALC (Addr: 08H)
(6)
Set up LMTH1 and RGAIN1 bits (Addr: 0BH)
(7)
Set up LMTH0, RGAIN0, LMAT1-0 and ALC bits (Addr: 07H)
When PMADL or PMADR bit is “1”, ALC for DAC path is disabled.
(8)
Set up the input digital volume (Addr: 09H and 0CH)
When PMADL = PMADR bits = “0”, IVL7-0 and IVR7-0 bits should be set to “91H”(0dB).
(9)
Set up the output digital volume (Addr: 0AH and 0DH).
When DVOLC bit is “1” (default), DVL7-0 bits (Addr=0AH) set the volume of both channels. After DAC is
powered-up, the digital volume changes from default value (0dB) to the register setting value by the soft
transition.
(10)
Set up Speaker Output Mode: SPKMN bit: “0”
“1” (Stereo SPK Mode)
SPKMN bit should be set to “0” in Mono SPK Mode or High Power Mono SPK Mode.
