6.15 Analog Input Advisory Volume (Address 11h)

6.15.1 Analog Input Advisory Volume

Defines the maximum analog input volume level used by the class H controller to determine the appropri-

ate supply for the HP and Line amplifiers.

6.16 Digital Input Advisory Volume (Address 12h)

6.16.1 Digital Input Advisory Volume

Defines the maximum digital input volume level used by the class H controller to determine the appropri-

ate supply for the HP and Line amplifiers.

Note:

Between the headphone and line, the final output voltage from the charge pump is dictated by

the highest required advisory volume. When any respective amplifier is powered down, the charge pump’s

voltage automatically adjusts to the appropriate level.
