Low Frequency Power Amplifier Circuit for TV 12 29.750.3 78.00.3 20.00.3 (10.0) (10.0) R1.8 1 1.70.1 (12.5) * * * * 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 overvoltage and - current. Temperature protection 1.80.15 + 0.1 0.25 - 0.05 2.54 1.450.15 s Features * Wide operating supply voltage range (10 to 40V) * Little distortion and noise * Fewer external components 0.6 (1.3) The AN5275 is an audio power IC developed for TV sound output (15W x 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.
