TDA2030 200 watt amp low cost audio power amplifier
This TDA2030 200 watt amp low cost audio power amplifier can deliver high output audio power up to 200 watts on a 2 – 4 ohms load impedance . This 200 watt amp high power audio amplifier is build around the TDA2030 audio amplifier IC which normally can deliver up to 14 watts on a 4 ohm load , but if is used in bridge mode an if we use some cheap power transistors can be created a 200 watts high power audio amplifier .
All transistors and the ICs must be mounted on a heatsink to prevent over temperature damage . For small value resistors ( 1 ohm ,2.2 ohms ) use 2 -5 watts resistors .
The design of this audio amplifier circuit is very simple and require few external components .
For better performance you can use a power supply which can deliver more power than 28 volts (+/- 14 volts ) but no more than 44 volts ( +/- 20 volts) .
