Pin Descriptions

Pin Number

Pin Name

Function

1

RINN

Negative differential audio input for right channel.

2

RINP

Positive differential audio input for right channel.

3

AVDD

5V Analog VDD

4

VREF

Analog reference for gain control section.

5

VOLUME

DC voltage that sets the gain of the amplifier.

6

REF GND

Ground for gain control circuitry. Connect to AGND. If using a DAC to control the

volume, connect the DAC ground to this terminal.

7

AGND1

Analog GND

8

FADE

Input for controlling volume ramp rate when cycling SD or during power-up. A

logic low on this pin places the amplifier in fade mode. A logic high on this pin

allows a quick transition to the desired volume setting.

9

LINP

Positive differential audio input for left channel.

10

LINN

Negative differential audio input for left channel.

11, 20

PGNDL

Power ground for left channel H-bridge.

12, 19

PVCCL

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

13, 14

LOUTN

Class-D 1/2-H-bridge negative output for left channel.

15

BSLN

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

16

BSLP

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

17, 18

LO UTP

Class-D 1/2-H-bridge positive output for left channel.

21

VCLAMPL

Internally generated voltage supply for left channel bootstrap capacitors.

22

CO SC

I/O for charge/discharging currents onto capacitor for ramp generator triangle

wave biased at V2P5.

23

RO SC

Current setting resistor for ramp generator. Nominally equal to 1/8*VCC.

24, 28

AGND

Analog GND

25

MUTE

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

26

AVCC

High-voltage analog power supply (7V to 15V)

27

V2P5

2.5V Reference for analog cells, as well as reference for unused audio input

when using single-ended inputs.

29

SD

Shutdown signal for IC (low = shutdown, high = operational). TTL logic levels with

compliance to VCC.

30

VCLAMPR

Internally generated voltage supply for right channel bootstrap capacitors.

31, 40

PGNDR

Power ground for right channel H-bridge.

32, 39

PVCCR

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

33, 34

ROUTP

Class-D 1/2-H-bridge positive output for right channel.

35

BSRP

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

36

BSRN

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

37, 38

ROUTN

Class-D 1/2-H-bridge negative output for right channel.
