19 I Sets the maximum volume for single ended operation. DC voltage range is 0 to VDD.
Sets the difference between BTL volume and SE volume. DC voltage range is 0 to
21 I Terminal for dc volume control. DC voltage range is 0 to VDD.
Input MUX control. When logic high, RHPIN and LHPIN inputs are selected .When
logic low, RLINEIN and LLINEIN inputs are selected.
Output MUX control. When this terminal is high, SE outputs are selected. When this
terminal is low, BTL outputs are selected.
14 O Left channel positive audio output.
