Function
O ^{Right channel negative audio output}
-
Supply voltage terminal for power stage
I
Right channel headphone input,selected when HP/LINE is held high
I
Right channel line input, selected when HP/LINE is held low
Common right channel input for fully defferential input. AC ground for
I
single-ended inputs.
-
Supply voltage terminal
I
Common left channel input for fully differential input. AC ground for
single-ended inputs.
I
Left channel line input, selected when HP/LINE is held low
I
Left channel headphone input,selected when HP/LINE is held high.
O ^{Left channel negative audio output}
O Left channel positive audio output.
I
Places the amplifier in shutdown mode if a TTL logic low is placed on
this terminal.
I
Places the amplifier in fade mode if a logic low is placed on this
termnal; normal operation if a logic high is placed on this terminal.
I
Tap to voltage divider for internal midsupply bias generator used for
analog reference.
-
Analog power supply ground
Sets the maximum volume for single ended operation.DC voltage
I
range is 0 to VDD
Sets the difference between BTL volume and SE volme. DC voltage
I
range is 0 to VDD
I
Terminal for dc volume control. DC voltage range is 0 to VDD
Input MUX control. When logic high,RHPIN and LHPIN inputs are
I
selected. When logic low,RLINEIN and LLINEIN inputs are selected
I
Output MUX control. When this terminal is high,SE outputs are
selected.When this terminal is low, BTL outputs are selected
O ^{Right channel positive audio output.}
