Overview
TA8261AH TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8261AH Max Power 40 W BTL × 4CH Audio Power IC The TA8261AH 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.
