Overview
TA8275H TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8275H Max Power 41 W BTL ´ 4 ch Audio Power IC The TA8275H is 4 ch BTL audio power amplifier for car audio application.
This IC can generate more high power: POUTMAX = 41 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.
