DIY Power Amplifier

Two channels pure post-stage amplifier board kit TDA2030A. Pure power amp simply amplifies the volume without a preamplifier circuit. The audio input directly drives the speakers without any modification, resulting in authentic, pure, and natural sound. The amplifier board features two classic TDA2030 amplifier ICs, providing pure power amplification. It operates with a single power supply, with an input voltage range of AC 9V-15V. With a rational component layout, it delivers strong power (15Wx2), almost no static noise, excellent audio quality, and requires fewer external components. It’s easy to install and suitable for home audio system conversions or installations, widely used with various speakers.

Principle: The power amplifier IC TDA2030 board is well-designed, with a reasonable component layout, minimal static noise, high fidelity, low distortion, and requires few external components. It provides a simple assembly process and high power output (15W + 15W). It’s suitable for electronics enthusiasts, audiophiles, and students for DIY projects.

Performance Parameters:

• Input voltage: AC 9-15V or DC 9-15V (Note: distinguish polarity for DC input; polarity is irrelevant for AC input)
• Output power: Po = 15W + 15W (RL = 4Ω)
• Output impedance: 4-8 Ω
