Pin Number

Name

Function

1

RINN

Negative differential audio input for right channel

2

RINP

Positive differential audio input for right channel

3AVDD

5V Analog VDD

4

VREF

Analog reference for gain control section

5

VOLUME

DC voltage that sets the gain of the amplifier

6REFGND

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

LOUTP

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

21

VCLAMPL

Internally generated voltage supply for left channel bootstrap capacitors.

22

COSC

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

wave biased at V2P5

23

ROSC

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
