TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8251AHQ
Max Power 30W BTL × 4ch Audio Power IC
The TA8251AHQ is 4ch BTL audio power amplifier for consumer
application.
It is designed low distortion ratio for 4ch BTL audio power
amplifier, built−in stand−by function, muting function and
junction temperature detection circuit. Additionally, the AUX.
amplifier is built−in, it can make the beep signal etc. Output to 2
channels (out1 and 4).
It contains various kind of protectors for car audio.
