This kit teaches how amplifiers take a small signal and "magnify" it
to drive a small speaker or headphone. It's based on the
LM386 Low Voltage Power Amplifier. This chip is not a toy;
it's designed to be used in a variety of consumer
electronics applications such as AM-FM radio amplifiers,
portable tape or CD players, intercoms, TV sound systems,
etc. Provides up to 1 watt of low-distortion audio power.
Harmonic distortion is 0.2%; voltage gain to 46dB. Power
requirement is 5 to 10v DC, size 2.25" x 2.75"
This kit uses SURFACE MOUNT parts.
