Description

1

Analog Positive supply voltage

/CAP_DC

2

CAP discharge. This pin is functional only as the system is shutdown.

HPIN

3

Headphone input detection.(refer to Page.14 for detection levels)

A logical low sets BTL mode, a logical high sets SE mode.

ROUT

7

SE right channel output

8

Positive supply voltage for right channel of power amplifier

BTL+

9

Positive output of BTL

10

Positive supply voltage for left channel of power amplifier

LOUT/BTL-

11

SE left channel output or negative output of BTL

12

Negative supply voltage

13

Negative supply voltage for left channel of power amplifier

SD_MODE

15

The shutdown mode selects the shutdown logic level of the SD pin.

SD

16

SD_MODE = 0, the device is shutdown when SD is logic low.

SD_MODE = 1, the device is shutdown when SD is logic high.

17

Negative supply voltage

18

Digital Ground

/DAC_SD
