The Champion...a tiny audio amplifier module that can deliver 7W peak power!

摘要

BOTH THE CHAMP and Pre-CHAMP have had a very long run since they hit the scene in the February & July 1994 issues of Silicon Chip. In fact, many thousands of each have been built. That's because they were cheap, easy to build and did the basic job required of them - to give just about anything the ability to drive a speaker and make a sound, be it a radio, sound effects generator, music player, communications receiver - whatever. But while they will no doubt continue to be popular, they are now over-shadowed by our new module, the "Champion". It dances all around the Champ, evading all of its jabs and delivering a knock-out combination of convenient connectors, higher power, lower minimal operating voltage, much lower distortion and noise, mute and standby features and input mixing.
