DIY LM1876 Audio Amplifier Project


Our friends over at Electro Labs has a new project out, it is a DIY LM1876 Audio Amplifier Project. As usual it is a start to finish project that has full details so you can build your own.

“This is an audio power amplifier based on LM1876 which can deliver up to 20W per channel into 4 or 8 ohm load and guarantees less than 0.1% THD + N (Total Harmonic Distortion + Noise).

The amplifier is powered by -15 0 15 VAC symmetrical supply. The full bridge diode rectifier and the smoothing capacitors convert the AC input to ±21 VDC which is used to power LM1876. The inductors on the AC input line reduces the noise arising from the mains line.”
