Circuit diagram of 35 watts bridge amplifier using tda2030 however you can get more 35w output on tda2030 in a bridged connection with a 15v power supply. 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. Above is the circuit diagram for this tda2030 based amplifier circuit.
There is a resistor r4 between pin 2 and 4 we called that resistor as feedback resistor.
For example the super bridge 120 watts i love it. You will see that have very few parts. The r3 determines the input impedance of the ic. So that it allows only the high frequency audio signal.
