TA8252H
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8252H
Max Power 37W BTL 脳 4ch Audio Power IC
The TA8252H is 4ch BTL audio power amplifier for car audio
application.
This IC can generate more high power: P
OUT
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鈭抜n stand鈭抌y function, muting function,clip
detector,and diagnosis circuit.
Additionally, the AUX.amplifier is built鈭抜n, 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.
