SUBWOOFER AMPLIFIER TDA8954TH NON SMD DOWNLOAD GERBER PCB LAYOUT
Hello friends, in this video, I will assemble the TDA8954TH power amplifier which is equipped with a subwoofer filter and bass boost. The following is a schematic of the TDA8954TH power amplifier circuit. the amplifier circuit is quite simple and does not require any external components. I also added a subwoofer filter circuit that uses a dual IC op-amp that can use IC NE5532, 4558, and others. I have also added the opamp supply, it is regulated using the BD139 and BD140 transistors which can be regulated by changing the Zener diode value.
PSU Requirements:
Minimum Voltage: 12VDC Symmetrical
Maximum: 42VDC Symmetrical
Output Power @ 20Hz 35VDC: 300W RMS @ 8Ohm
