Description

The TA8259H is 4 ch BTL audio power amplifier for car audio application.

This IC can generate more high power: POUT MAX = 37 W as it is included the pure complementary PNP and NPN transistor output stage.

TA8259H 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).

TA8259H contains various kind of protectors for car audio use.
