Description

The TA8277H is 4 ch BTL audio power amplifier for car audio application.

This IC can generate more high power: POUTMAX = 43 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 and muting function.

Additionally, the AUX amplifier of the TA8277H and various kind of protector for car audio use is built-in.
