Panasonic AN5275 Datasheet

■ Overview

The AN5275 is an audio power IC developed for TV

sound output (15W×2Ch.).

High density mounting is possible and it can contribute
to cost reduction, because it requires fewer external com­ponents.

It incorporates various protective circuits to provide high

reliability and breakage resistance.

■ Features

•

Wide operating supply voltage range (10 to 40V)

•

Little distortion and noise

•

Fewer external components

· BS (boot-strap) electrolytic capacitor not required

•

Audio muting function built-in

•

Very small shock noise at power ON/OFF

•

Various protective circuits built-in

· Load short-circuit protection. Protection against over-
voltage and – current. Temperature protection
