Amplifier board for two LM3886 with parallel connection.

This board is for a power amplifier project that uses two LM3886 chips per channel, in a circuit with parallel connection. At 8 ohm load, the output power of the amplifier is of the order of 50 watts, for a 4 ohm 100 watts. The amplifier design uses four LM3886 chips. The LM3886 is connected by a non-inverting amplifier circuit. The development of the printed circuit board was carried out taking into account that the power ground (power supply) and the signal ground were separated. The signal ground is in the middle and is surrounded by power ground. When assembling the amplifier, high-quality Mundorf and Nichicon capacitors will be used.

    Quality of the PCB was great. Delivery time very acceptable.
    Good solderability, EMI, and overall quality. On-point dimensions for DIN connector.
    Good Quality, Fast Shipping. And, Faster than ordering in my country. :D
    My parts were machined quickly and shipped very fast. Excellent quality machining and all dimensions are in tolerance and price was lower than the competition. Expectations were exceeded. I will defin...
