Tda2030a Subwoofer Amplifier Circuit Diagram. For better performance this circuit needs split power supply with one amps. So that it allows only the high frequency audio signal.
And transistor bd249 or tip31 or tip41 or c1061 and bd250 or tip32 or tip42 or a671. For example the super bridge 120 watts i love it. We have connected a 2 2uf capacitor in series to the non inverting pin of the tda2030 here it is acting as the high pass filter.
Tda2030 ic amplifier circuit diagram the required components used in tda2030 ic subwoofer circuit are audio jack pin ic tda2030 ic resistors three 100k one 4 7 k and one 0 ohm capacitors like one 100 mf two 0 1 mf two 2 2 mf one 22mf one in4007 diode one speaker 12v battery and one variable resistor with 22k value.
It provides 14 watts output by adding another stage it may give output upto 30 watts. After ordering the kit on ebay search for tda2030a audio power amplifier diy kit i received a version 1 0 pcb made by xy hi fi with components and a short chinese manual on what was needed to solder the kit in stereo mode ocl or in mono mode btl or bridge. This circuit is constructed by using tda2030 ic and this is intended for use as a low frequency class ab amplifier. A single tda2030 ic can deliver up to 15 watts output.
