DESCRIPTION
– Power ground
O Left channel negative audio output
– Supply voltage terminal for power stage
I Left channel headphone input, selected when HP/LINE is held high
I Left channel line input, selected when HP/LINE is held low
I Common left channel input for fully differential input. AC ground for single-ended inputs.
– Supply voltage terminal
I Common right channel input for fully differential input. AC ground for single-ended inputs.
I Right channel line input, selected when HP/LINE is held low
I Right channel headphone input, selected when HP/LINE is held high
O Right channel negative audio output
O Right 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 terminal; normal operation if a logic
high is placed on this terminal
I Tap to voltage divider for internal mid-supply bias generator used for analog reference
– Analog power supply ground
I Sets the maximum volume for single ended operation. DC voltage range is 0 to V_DD.
I Sets the difference between BTL volume and SE volume. DC voltage range is 0 to V_DD.
I Terminal for dc volume control. DC voltage range is 0 to V_DD.
I
Input MUX control. When logic high, RHPIN and LHPIN inputs are 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 Left channel positive audio output.
