TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8266HQ
Max Power 35 W BTL × 4 ch Audio Power IC
The TA8266HQ is 4 ch BTL audio power amplifier for car audio
application.
This IC can generate more high power: P
OUT
MAX = 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, and
diagnosis circuit which can detect output to V
CC
/GND short and
over voltage input mode.
Additionally, the AUX amplifier and various kind of protector
for car audio use is built-in.

Note 1: Install the product correctly. 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.
