AN5275
15W × 2Ch. Low Frequency Power Amplifier Circuit for TV
s 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 com-
ponents.
It incorporates various protective circuits to provide high
reliability and breakage resistance.
s 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
