TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8264AH
Max Power 41 W BTL × 4 ch Audio Power IC
TA8264AH
The TA8264AH 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, muting function, and
diagnosis circuit which can detect output to VCC/GND short and
over voltage input mode.
Additionally, the AUX amplifier and various kind of protector
for car audio use are built-in.
