DESCRIPTION
GND/HS 1, 12,
13, 24
Ground connection for circuitry, directly connected to thermal pad
HP/LINE 16 I Input MUX control input, hold high to select LHP IN or RHP IN (5, 20), hold low to select LLINE IN or
RLINE IN (4, 21)
LBYPASS 6 Tap to voltage divider for left channel internal mid-supply bias
LHP IN 5 I Left channel headphone input, selected when HP/LINE terminal (16) is held high
LLINE IN 4 I Left channel line input, selected when HP/LINE terminal (16) is held low
LOUT+ 3 O Left channel + output in BTL mode, + output in SE mode
LOUT– 10 O Left channel – output in BTL mode, high-impedance state in SE mode
LV
DD
7 I Supply voltage input for left channel and for primary bias circuits
MUTE IN 11 I Mute all amplifiers, hold low for normal operation, hold high to mute
MUTE OUT 9 O Follows MUTE IN terminal (11), provides buffered output
NC 17, 23 No internal connection
RBYPASS 19 Tap to voltage divider for right channel internal mid–supply bias
RHPIN 20 I Right channel headphone input, selected when HP/LINE terminal (16) is held high
RLINEIN 21 I Right channel line input, selected when HP/LINE terminal (16) is held low
ROUT+ 22 O Right channel + output in BTL mode, + output in SE mode
ROUT– 15 O Right channel – output in BTL mode, high impedance state in SE mode
RV
DD
18 I Supply voltage input for right channel
SE/BTL 14 I Hold low for BTL mode, hold high for SE mode
SHUTDOWN 8 I Places entire IC in shutdown mode when held high, I
DD
= 5 µA
TJ 2 O Sources a current proportional to the junction temperature. This terminal should be left unconnected
during normal operation. For more information, see the junction temperature measurement section of
this document.
