lm3886 chipamp


Gainclone or chipamp is a term commonly used to describe a type of audio amplifier made by do-it-yourselfers. The Gainclone is probably the most commonly built and well-known amplifier project amongst hobbyists. It is simple to build and involves only a few readily accessible, inexpensive parts.

In 1999, 47 Labs introduced the Gaincard amplifier, which had fewer parts, less capacitance and simpler construction than anything preceding it. The DIY community started building replicas or ‘clones’ of the Gaincard using integrated circuits from National Semiconductor and other manufacturers. Most designs are very effective and produce high quality sound, even though some audiophiles consider chip-based amplifiers to be inferior to their discrete counterparts.
