Function

1

OUT_A

O

H-bridge A output.

2

PVCC_A

P

Power supply for H-bridge A not connected to PVCC_B or AVCC.

3

SHDN

I

Shutdown signal for IC (low = shutdown, high = operat ional). TTL logic levels with compliance to AVCC.

4

MUTE

I

Alogic high on this pin disables the outputs. A low on this pin enables the outputs. TTL logic levels with

compliance to AVCC.

5

IN_A

I

Audio input for channel A.

6

DGND

P

Digital GND

7

IN_B
