Pin Description

1,12,13,24

NAME

GND/HS

I/O

FUNCTION

Ground connection for circuitry, directly connected to thermal pad.

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.

LOUT+

LLINE IN

LHP IN

Left channel + output in BTL mode, + output in SE mode.

Left channel line input, selected when HP/ pin is held low.

Left channel headphone input, selected when HP/pin is held high.

LBYPASS

LVDD

SHUTDOWN

Connect to voltage divider for left channel internal mid-supply bias.

Supply voltage input for left channel and for primary bias circuits.

Shutdown mode control signal input, places entire IC in shutdown mode when held high,

_DD= 5µA.

MUTE OUT

LOUT-

MUTE IN

SE/BTL

ROUT-

Follows MUTE IN pin, provides buffered output.

Left channel - output in BTL mode, 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).

HP/LINE

17,23

RVDD

Supply voltage input for right channel.

RBYPASS

RHP IN

RLINE IN

ROUT+

Connect to voltage divider for right channel internal mid-supply bias.

Right channel headphone input, selected when HP/pin is held high.

Right channel line input, selected when HP/pin is held low.

Right channel + output in BTL mode, + output in SE mode.
