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.
