Common left input for fully differential input. AC ground for single-ended
inputs.
Left channel line input, selected when
SE/
Left channel positive output in BTL mode and positive output in SE mode.
Left channel negative output in BTL mode and high-impedance in SE mode.
The input for PC Beep mode. PC-BEEP is enabled when a > 1-V (peak-to-peak)
square wave is input to PC-BEEP or PCB ENABLE is high.

HP/
terminal is held low, the line BTL inputs (LLINEIN or RLINEIN [5,
23]) are active.
Power supply for output stage.
Right channel headphone input, selected when
Common right input for fully differential input. AC ground for single-ended
inputs.
Right channel line input, selected when
SE/
Right channel positive output in
BTL
mode and positive output in SE mode.
Right channel negative output in
BTL
mode and high-impedance in SE mode.
When held low, this terminal place the entire device, except PC-BEEP detect
circuitry, in shutdown mode.
Input and output MUX control. When this terminal is held high, the LHPIN or
RHPIN and SE output is selected. When this terminal is held low, the LLINEIN
or RLINEIN and BTL output are selected.
