Description

The TA8252H is 4ch BTL audio power amplifier for car audio application.

This TA8252H can generate more high power: POUT MAX = 37W as it is included the pure complementary PNP and NPN transistor output stage.

TA8252H is designed low distortion ratio for 4ch 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 channnels (out 1 and 4).It contains various kind of protectors for car audio use.
