General Description: The TA8276H is 4 ch BTL audio power amplifier for car audio application. This IC can generate more high power: POUTMAX = 35 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, output clipping detection and diagnosis circuit which can detect output to VCC/GND short and over voltage input mode. Additionally, the AUX amplifier and various kind of protector for car audio use are built-in.  Circuit Diagram: 35 W BTL x 4 ch Audio Power IC Datasheet for TA8276:   Download
