TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8273H
Max Power 47 W BTL × 4 ch Audio Power IC
The TA8273H is 4 ch BTL audio power amplifier for car audio
application.
This IC can generate more high power: P
OUT
MAX = 47 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,
output offset voltage and over voltage input mode.
Additionally, the AUX amplifier and various kind of protector
for car audio use are built-in.
