Description
Ground connection for circuitry, directly connected to thermal pad
(only in TSSOP-P package).
O Shutdown mode control signal input, sources a current proportional
to the junction temperature. This pin should be left unconnected
during normal operation. For more information, see the junction
temperature measurement section of this document.
O Left channel + output in BTL mode, + output in SE mode.
I Left channel line input, selected when HP/ LINE pin (16) is held low.
I Left channel headphone input, selected when HP/ LINE pin (16) is
held high.
Connect to voltage divider for left channel internal mid-supply bias.
I Supply voltage input for left channel and for primary bias circuits.
I Shutdown mode control signal input, places entire IC in shutdown
mode when held high, IDD= 0.5µA.
O Follows MUTE in pin (11), provides buffered output.
O Left channel - output in BTL mode, high-impedance state in SE
mode.
I Mute control signal input, hold low for normal operation, hold high to
mute.
I Mode control signal input, hold low for BTL mode, hold high for SE
mode.
O Right channel - output in BTL mode, high impedance state in SE
mode.
I MUX control input, hold high to select headphone inputs (5,20),
hold low to select line inputs (4,21).
