Overview

TA8271HQ TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8271HQ Max Power 41 W BTL × 4 ch Audio Power IC The TA8271HQ 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.

Otherwise, it may result in break down, damage and/or degradation to the product or equipment.
Note 2: These protection functions are intended to avoid some output short circuits or other abnormal conditions temporarily.
These protect functions do not warrant to prevent the IC from being damaged.
- In case of the product would be operated with exceeded guaranteed operating ranges, these protection features may not operate and some output short circuits may result in the IC being damaged.
