LM386 amplifier
The
LM386 loudspeaker amplifier is an integrated circuit (IC)
in a housing with eight pins, numbered from pin 1 at the bot-
tom left corner to pin 8 at the top left corner. Pin 4 (bottom
right) is the negative terminal of the power supply. The ampli
-
fier operates at 9 V and provides 0.5 W to the loudspeaker.
The
loudspeaker exhibits a resistance of 8 Ohm and can
tolerate up to 0.5 W. The volume depends mainly on how the
loudspeaker is mounted. A pleasant sound is only achieved by
installing the loudspeaker in the housing.
