Technical content

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. n 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 ICs for Audio Common Use AN5275 15W · 2Ch.
