Wiring & diagram Info

This is a 200 Watt Amplifier Circuit Diagram that uses a TDA2030 IC which is an audio power amplifier 200 watt low cost. The 200 watts can be achieved with a load impedance of 4 ohms. The TDA2030 can typically provide up to 14 watts into a 4 ohm load, but if used in bridge mode and we use some cheap power transistors we can get to 200 watt. The design of this amplifier schema 200 watt audio is very simple and requires few external components. For best performance, you can use a source of 28 volts (+ / - 14 volts), not more than 44 volts (+ / - 20 volts).

 As you can see in the diagram, for this power amplifier schema you need high capacity capacitors and a power supply high current. All transistors and ICS should be mounted on a heat sink to prevent damage by temperature. For small value resistors (1 ohm, 2.2 ohm) resistors use 2-5 watts.
