DIY KIT 41- TDA2030A Electronic Mono Audio Power Amplifier Board

TDA2030A is widely used as a Hi-Fi audio amplifier in computer speakers.
It has the current limiter as well as thermal shutdown functions.

Specifications:
Output Power: Maximum 18W
Supply Voltage: DC 9V-24V (recommended DC 12V, this voltage to the heat sink requirements are very low.

The maximum supply of this board is actually up to 40V, but you need to change the board’s electrolytic capacitor C1. The capacitor voltage value should be higher than the supply voltage.
Static Current: about 25mA (disconnect to tone, connect to 8Ω speaker, 12V power supply)
Speaker Impedance: 4Ω-8Ω
Total harmonic distortion: THD 0.08%(Po=0.1 to 14W,RL=4Ω)
SNR: 94dB-106dB(1W-15W)
Heat: The higher the supply voltage, the higher the heat is generated.
