Product Summary
The TA8264AH is a 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. The TA8264AH 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.
