GAIN0

GAIN1

I For gain control: Bit 0

I For gain control: Bit 1

LLINEIN

LHPIN

I Line input for Left channel, available when pin15 is held low.

I Headphone input Left channel, available when pin15 is held high.

PVDD

RIN

I Power supply voltage.

Differential input for right channel. And for single-ended inputs is also AC

I ground.

LIN

PC-BEEP

Differential input for Left channel. And for single-ended inputs is also AC

I ground.

I

PC-BEEP mode input. When at least eight continuous >1-VPP square

waves is input to this pin, PC-BEEP is enabled.

HP/ LINE

Input of MUX control. Being high to select the inputs of Pin6, 20, and low

I to select inputs of PIN 5, 23.

SE/ BTL

I Low for BTL mode, high for SE mode.

VDD

RHPIN

RLINEIN

I Analog VDD supply voltage

I Right channel headphone input, selected when pin17 is held high.

I Headphone input right channel, available when pin17 is held low.

SHUTDOWN I In shutdown mode when held low, expect PC-BEEP remains active.
