Ground connection for circuitry, directly connected to thermal pad
(only in TSSOP-P package).
Shutdown m ode control signal input, sources a current proportional
to the junction temperature. This pin should be left unconnected
during normal operation. For more inform ation, see the junction
temperature measurem ent section of this document.
Left channel + output in BTL mode, + output in SE m ode.
Left channel line input, selected when HP/ LINE pin (16) is held low.
Left channel headphone input, selected when HP/ LINE pin (16) is
held high.
Connect to voltage divider for left channel internal mid-supply bias.
Supply voltage input for left channel and for prim ary bias circuits.
Shutdown m ode control signal input, places entire IC in shutdown
mode when held high, I
Follows MUTE in pin (11), provides buffered output.
Left channel - output in BTL m ode, high-impedance state in SE
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).
