FUNCTION

Ground connection for circuitry, directly connected to thermal pad.
Source a current inversely to the junction temperature. This pin should be left uncon-
nected during normal operation. For more information, see the junction temperature
measurement section of this document.
Left channel + output in BTL mode, + output in SE mode.
Left channel line input, selected when HP/ pin is held low.
Left channel headphone input, selected when HP/pin is held high.

SHUTDOWN
Connect to voltage divider for left channel internal mid-supply bias.
Supply voltage input for left channel and for primary bias circuits.
Shutdown mode control signal input, places entire IC in shutdown mode when held high,

= 5μA.
Follows MUTE IN pin, provides buffered output.
Left channel - output in BTL mode, high impedance state in SE mode. Supply VDD/2 to
the phone jacket in HP-IN mode.
Mute control signal input, hold low for normal operation, hold high to mute.
Mode control signal input, hold low for BTL mode, hold high for SE mode.
Right channel - output in BTL mode, high impedance state in SE mode.
MUX control input, hold high to select headphone inputs (5,20), hold low to select line
inputs (4,21).
This pin can activate the HP-IN mode to supplied the VDD/2 at LOUT- onto the phone
jacket. So the DC blocking capacitors can be removed in HP-IN type (like SE mode
except no DC blocking capacitors). Hold high to activate this function. If this function is
not used, it should be strongly tied to low.
Supply voltage input for right channel.
Connect to voltage divider for right channel internal mid-supply bias.
Right channel headphone input, selected when HP/pin is held high.
Right channel line input, selected when HP/pin is held low.
Right channel + output in BTL mode, + output in SE mode.
The output power can be clamped by setting a low bound voltage to this pin. The high
bound voltage will be generated internally. The output voltage will be clamped between
high/low bound voltages. Then the output power is limited. It is weakly pull-low inter-
nally, let this pin floating or tied to GND can deactivate this function.
