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, intercom's, TV sound systems, etc. Provides up to 1 watt of low distortion audio power. Harmonic distortion is 0.2% with a voltage gain of up to 46 dB.
