NAME

1

SD

I

Shutdown logic input for audio amp (LOW = outputs Hi-Z, HIGH = outputs enabled). TTL logic levels

with compliance to AVCC.

2

FAULT

O

Open drain output used to display short circuit or dc detect fault status. Voltage compliant to AVCC.

Short circuit faults can be set to auto-recovery by connecting FAULT pin to SD pin. Otherwise, both

short circuit faults and dc detect faults must be reset by cycling PVCC.

3

LINP

I

Positive audio input for left channel. Biased at 3 V.

4

LINN

I

Negative audio input for left channel. Biased at 3 V.

5

GAIN0

I

Gain select least significant bit. TTL logic levels with compliance to AVCC.

6

GAIN1

I

Gain select most significant bit. TTL logic levels with compliance to AVCC.

7

AVCC

P

Analog supply

8

AGND

—

Analog signal ground. Connect to the thermal pad.

9

GVDD

O

High-side FET gate drive supply. Nominal voltage is 7V. Also should be used as supply for PLIMIT

function.

10

PLIMIT

I

Power limit level adjust. Connect a resistor divider from GVDD to GND to set power limit. Connect

directly to GVDD for no power limit.

11

RINN

I

Negative audio input for right channel. Biased at 3 V.

12

RINP

I

Positive audio input for right channel. Biased at 3 V.
