20W Hi-Fi Audio Power Amplifier

TDA2030 is most popular, high quality - low cost audio power amplifier and successive version of TDA2006. Typically TDA2030 deliver 14W in 24V with 4Ω output load and 8W in 8Ω output load. Because of it’s wider power bandwidth (10Hz to 140 kHz) and extremely small amount of distortion (0.1% - 0.5%), TDA2030 deliver excellent sound quality with higher performance. In this project we design basic version of TDA2030 mono power amplifier for general use and its design to work with 9V – 24V (500mA) Power Supply Unit.

When building the circuit it is recommended to use PCB design and its important to attach suitable heat-sink to the TDA2030. In this design it is not necessary to have electrical isolation between the IC and the heat-sink.
