Pin Description
PIN
NAME
I/O
FUNCTION
1,12,13,24
GND/HS
Ground connection for circuitry, directly connected to thermal pad.
2
TJ
O
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.
3
LOUT+
O
Left channel + output in BTL mode, + output in SE mode.
4
LLINE IN
I
Left channel line input, selected when HP/ pin is held low.
5
LHP IN
I
Left channel headphone input, selected when HP/pin is held high.
6
LBYPASS
Connect to voltage divider for left channel internal mid-supply bias.
7
LVDD
I
Supply voltage input for left channel and for primary bias circuits.
8
SHUTDOWN
I
Shutdown mode control signal input, places entire IC in shutdown mode when held
high, IDD = 5A.
9
MUTE OUT
O
Follows MUTE IN pin, provides buffered output.
10
LOUT-
O
Left channel - output in BTL mode, high impedance state in SE mode.
11
MUTE IN
I
Mute control signal input, hold low for normal operation, hold high to mute.
14
SE/ BTL
I
Mode control signal input, hold low for BTL mode, hold high for SE mode.
15
ROUT-
O
Right channel - output in BTL mode, high impedance state in SE mode.
16
HP/ LINE
I
MUX control input, hold high to select headphone inputs (5,20), hold low to select line
inputs (4,21).
17,23
NC
18
RVDD
I
Supply voltage input for right channel.
19
RBYPASS
Connect to voltage divider for right channel internal mid-supply bias.
20
RHP IN
I
Right channel headphone input, selected when HP/pin is held high.
21
RLINE IN
I
Right channel line input, selected when HP/pin is held low.
22
ROUT+
O
Right channel + output in BTL mode, + output in SE mode.
Thermal Pad
Recommend connecting the Thermal Pad to the GND for excellent power dissipation.
