FUNCTIONAL DESCRIPTION
FUNCTIONAL INTERNAL BLOCK DESCRIPTION
Line Outputs
The SGTL5000 contains a stereo line output. The line
output has a dedicated gain stage that can be used to adjust
the output level. The CHIP_LINE_OUT_VOL controls the line
level output gain.
The line outputs also have a dedicated mute that is
controlled by the register field CHIP_ANA_CTRL-
>MUTE_LO.
The line out volume is intended as maximum output level
adjustment. It is intended to be used to set the maximum
output swing. It does not have the range of a typical volume
control and does not have a zero cross detect (ZCD).
However the DAC digital volume could be used if volume
control is desired.
