Here we have a great quality double-sided PCB on which you can build an LM3886 based mono power amplifier.
The board is fully marked out for all resistor/capacitor values etc.
Perfect for use with our active crossover filter boards!
THIS LISTING IS FOR A PACK OF FIVE PCBS, SAVING YOU £2.50.
This is v1.1 of the board, with provision for an RCA connector for the input signal instead of a terminal block.
The board was designed in the UK.
These amplifiers are truly amazing, capable of delivering up to 68W, with extremely low THD and sporting many advanced features such as under/over voltage protection, thermal protection etc.
There's provision for a 0.1 ohm resistor for connecting boards in parallel.
Size: W 70mm H 35mm.
You will need the following low-cost components to build this amplifier:
1x LM3886 amplifier IC.
1x 1uF metallised polyester capacitor.
3x 100uF 50V electrolytic capacitor.
1x 22uF 50V electrolytic capacitor.
3x 22k 1% metal film resistor.
2x 1k 1% metal film resistor.
1x 3-way 5mm terminal block.
1x 2-way 5mm terminal block.
1x PCB mounted RCA socket.
You will need to attach a heat sink as the LM3886 is a powerful chip and dissipates a lot of heat. Please note when attaching the heatsink, the LM3886 backplate is at V-.
You will also need a way of powering the amp up. Check our other listings we can help you with that.
You will need access to a soldering iron.
For all relevant info on the LM3886 IC simply Google the datasheet.
IMPORTANT - INSTALLATION BY QUALIFIED PERSONS ONLY AS MAINS ELECTRICITY IS INVOLVED.

Buy it now normally £3.49 each, pack of five £14.95.
UK shipping £1.99 no matter how many you buy (combined shipping).
Rest of world shipping £3.49 no matter how many you buy (combined shipping).
Thanks for looking!
