Hello, i got a audio amplifier with IC TA8225H. (not home made)

and there is a low pass filter in it, but i can't find it. it cuts slowly around 100 hz. but 1000 hz can still be heard.


I tried to draw a diagram, (first time i try it btw.)


Hope someone can find the filter, so i can remove it.

ta8225h amplifier schematic

Your schematic does not show a Toshiba TA8225 audio amplifier IC.
Your schematic does not make sense.

Hmmm, do you know any ta8225 schematic ?
 

Audio amplifier

The schematic of a car radio amplifier using the TA8225H amplifier IC is in Toshiba's datasheet.
It shows a block diagram of the IC's circuit but no details.

The amplifier circuit shows a flat frequency response to above 100kHz without a lowpass filter.
