Overview
TA8252H TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8252H Max Power 37W BTL × 4ch Audio Power IC The TA8252H is 4ch BTL audio power amplifier for car audio application.
This IC can generate more high power: POUT MAX = 37W as it is included the pure complementary PNP and NPN transistor output stage.
It 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.
