47 Watt BTL Audio Power Amplifier 4-channel

General Description: The TA8273H is 4 ch BTL audio power amplifier for car audio  application.  This IC can generate more high power: POUTMAX = 47 W as it  is included the pure complementary PNP and NPN transistor  output stage.  It is designed low distortion ratio for 4 ch BTL audio power  amplifier, built-in stand-by function, muting function, and  diagnosis circuit which can detect output to VCC/GND short,  output offset voltage and over voltage input mode. Additionally, the AUX amplifier and various kind of protector  for car audio use are built-in.  Circuit Diagram: Datasheet for TDA8273: Download
