Audio Power Amplifier with TDA2030
This compact audio amplifier uses the TDA2030 integrated circuit to deliver up to 14 W of clean audio output into a 4 Ω speaker. It is ideal for small home or desktop audio projects where high fidelity is desired without a complex design.
Power Supply
The amplifier operates from a dual or single supply voltage ranging from 6 V to 18 V, with a nominal supply of 14 V. Standard diodes like 1N4001 or 1N4002 can be used for input protection.
