Terminal Functions

TERMINAL

I/O

DESCRIPTION

NAME

NO.

I/O

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

LVDD

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

RVDD

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, IDD = 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.
