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
