TA8260AH Datasheet, PDF (1/15 Pages) Toshiba Semiconductor – Max Power 40 W BTL × 4CH Audio Power IC

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8260AH
Max Power 40 W BTL × 4CH Audio Power IC
TA8260AH
The TA8260AH is 4 ch BTL audio power amplifier for car audio
application.
This IC can generate more high power: POUT MAX = 40 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, Clip
detector, and diagnosis circuit.
Additionally, the AUX. amplifier is built-in, it can make the beep
signal etc. output to 2 channels (OUT1 and 4).
It contains various kind of protectors for car audio use.
