Volume, Automute, and Mute
The TAS5028A provides individual channel and master volume controls. Each control provides an adjustment
range of +18.0618 dB to –100 dB in 0.25 dB increments. This permits a total volume device control range of
+36 dB to –100 dB plus mute. The master volume control can be configured to control six or eight channels.
The TAS5028A has a master soft mute control that can be enabled by a terminal or I
2
C command. The device
also has individual channel soft mute controls that can are enabled via I
2
C.
The soft volume and mute
update rates are programmable. The soft adjustments are performed using a soft
gain linear update with an I
2
C programmable linear step size at a fixed temporal rate. The linear soft gain step
size can be varied from 0.5 to 0.003906.
