Product Description

This is a PCB to build a high fidelity amplifier using National Semiconductor LM3886 IC. With the addition of a handful of parts and a suitable power supply, this module will deliver 68W into 4 ohms or 38W RMS into 8 ohms. This implements a complete LM3886 circuit, including Zobel network (RC) and Thiele Network (RL) at the output. It also has an RF filter at the amp input.

 

Recomended voltage-

with 4 ohm speakers - 28V-0-28V DC

With 8 ohm speaker - 32V-0-32V DC
