TA8271H

Max Power 41 W BTL x 4 ch Audio Power IC

Toshiba 

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic

TA8271H

Max Power 41 W BTL × 4 ch Audio Power IC

The TA8271H 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 and muting function.

Additionally, the AUX amplifier and various kind of protector

for car audio use is built-in.

Features
