Max Power 35W BTL 4CH Audio Power IC
Max Power 35 W BTL × 4 ch Audio Power IC
The is 4 ch BTL audio power amplifier for car audio application. This IC can generate more high power: POUTMAX = 35 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 is built-in.
