Two boards are needed for a stereo build. Mono board to allow for mono block construction.Input RFI/EMI filter prevents all pops and clicks from the switching of heavy loads as well as buzz associated with cell phones, WiFi, and other RF interference sources.Elaborate use of planes and pours to minimize ground bounce and ensure good THD performance across the audible frequency spectrum for the best audio quality possible.All components needed for good amplifier stability included in the circuit.

LM3886 layout fully optimized for high signal integrity.The key features of the LM3886DR are summarized below. The LM3886 Done Right circuit board is manufactured in Canada. With some careful parts scrounging, it is realistic to complete a stereo LM3886DR with power supply and home made chassis for less than $200. In addition, this circuit is intended to be a relatively inexpensive and more beginner-friendly project than, for example, the Modulus-86. My goal with the LM3886 Done Right (LM3886DR) is to ease the anxiety by combining a circuit which includes all the necessary components for good amplifier stability and good RF immunity with a PCB layout that is second to none. A poor layout will, best case, result in an amplifier that performs poorly and fails to meet the data sheet specifications of the LM3886 and, worst case, result in an unstable amplifier. Given these facts and the number of LM3886 PCB layouts available, it is understandable that a significant amount of anxiety surrounds the choice of which one to purchase.Ī good layout will ensure that the LM3886 lives up to its data sheet specs. This is certainly true for high-end audio design and also for high-power design. The PCB layout is a large part of the circuit - some say the layout is the circuit.
