DESCRIPTION

NAME

NO.

OUTPL

1

O

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

BSPL

2

P

Bootstrap supply (BST) for positive high-side FET of the left channel.

PVCCL

3

P

Power supply for left channel H-bridge. Right channel and left channel power supply inputs are

connected internally.

SD/FAULT

4

IO

TTL logic levels with compliance to AVCC. Shutdown logic input for audio amp (LOW, outputs Hi-Z;

HIGH, outputs enabled). General fault reporting includes Over-Temp, Over-Current, and DC Detect.

SD/ FAULT= High, normal operation, SD/ FAULT= Low, fault condition. Device will auto-recover once

the OT/OC/DC Fault has been removed.

LINP

5

I

Positive audio input for left channel. Biased at 2.5 V. Connect to GND for PBTL mode.

LINN

6

I

Negative audio input for left channel. Biased at 2.5 V. Connect to GND for PBTL mode.

GAIN_SEL

7

I

Gain select least significant bit. TTL logic levels with compliance to AVDD. Low = 20-dB Gain, High =

26-dB Gain, Floating = 26-dB Gain.

MODE_SEL

8

I

Mode select least significant bit. TTL logic levels with compliance to AVDD. Low = BD Mode with UV

Threshold = 7.5 V, High = 1SPW Mode with UV Threshold = 3.4V, Floating = 1SPW Mode with UV

threshold = 3.4V.

AVCC

9

P

Analog supply.
