Class-D Speaker Analog Output Volume Control
For the speaker outputs, the analog volume control has a range from 0 dB to –78 dB in 0.5-dB steps for
most of the useful range plus mute, as seen in Table 5-17 and Table 5-18. The implementation includes
soft-stepping logic.
Routing the DAC output signal to the analog volume control is done by writing to page 1 / register 35,
bits D7–D6. Changing the analog volume for the speaker is controlled by writing to page 1 / register 38,
bits D6–D0.
Routing the signal from the output of the analog volume control to the input of the speaker amplifier is
done by writing to page 1 / register 38, bit D7.
The analog volume-control soft-stepping time is based on the setting in page 0 / register 63, bits D1–D0.
5.6.9
Analog Outputs
Various analog routings are supported for playback. All the options can be conveniently viewed on the
functional block diagram, Figure 1-1.
