Description
This simple amplifier shows the LM386 in a high-gain
configuration (A = 200). For a maximum gain of only 20, leave out the 10 uF
connected from pin 1 to pin 8. Maximum gains between 20 and 200 may be realized
by adding a selected resistor in series with the same 10 uF capacitor. The 10k
potentiometer will give the amplifier a variable gain from zero up to the
maximum.
