Symbol

Pin

Description

1

Positive supply voltage for left channel of power amplifier

LOUT/BTL-

2

SE left channel output or negative output of BTL

3

Negative supply voltage

4

Negative supply voltage for left channel of power amplifier

LIN

5

Left channel input

SD_MODE

6

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

SD

7

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

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

8

Negative supply voltage

9

Digital Ground

/DAC_SD

10

DAC shutdown pin. /DAC_SD=0, DAC is shutdown. /DAC_SD=1, DAC is Active.
