Pin Descriptions

Pin Number

Package Name

Function

1, 8, 24

NC

No Connect, floating or connect to GND on PCB

2

RINN

Negative differential audio input for right channel.

3

RINP

Positive differential audio input for right channel.

4

MUTE

A logic-high on this pin disables the outputs and a logic low enables the outputs.

5

AVDD

5V Analog Supply (internally generated)

6

LINP

Positive differential audio input for left channel.

7

LINN

Negative differential audio input for left channel.

9, 16

PGNDL

Power ground for left channel H-bridge.

10, 15

PVCCL

Power supply for left channel H-bridge, not connected to PVCCR or AVCC.

11

LOUTN

Class-D H-bridge negative output for left channel.

12

BSLN

Bootstrap I/O for left channel, negative high-side FET.

13

BSLP

Bootstrap I/O for left channel, positive high-side FET.

14

LOUTP

Class-D H-bridge positive output for left channel.

17

SSMCTL

SSM ON/OFF Control. A Logic-Low enable SSM feature and a Logic-High

disable SSM feature. (Logic-High level complies to AVDD).

SSM mode will be turned ON if this pin is left floating after power-up, due to pull-

up resistor embedded.

18

PL

Reference voltage for power-limit function.

19

V2P5

2.5V Reference for analog cells.

20

AGND

Analog Ground

21

VCLAMP

Internally generated voltage supply for bootstrap capacitors.

22

AVCC

High-voltage analog power supply (4.5V to 15V)

23

SD

Shutdown signal for IC (low= shutdown, high = operational). Compliance to

AVCC.

25, 32

PGNDR

Power ground for right channel H-bridge.

26, 31

PVCCR

Power supply for right channel H-bridge, not connected to PVCCL or AVCC.

27

ROUTP

Class-D H-bridge positive output for right channel.

28

BSRP

Bootstrap I/O for right channel, positive high-side FET.

29

BSRN

Bootstrap I/O for right channel, negative high-side FET.

30

ROUTN

Class-D H-bridge negative output for right channel.

33

Thermal Pad

Connect to ground. Thermal pad should be soldered down on all applications to

secure the device properly to the printed wiring board.
