LM386 Audio Amplifier - Cornerstone Robotics
... Explanation: This amplifier shows the LM386 in a high-gain configuration (Gain = 200). For a maximum gain of only 20, leave out the 10 F capacitor C4 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 C4. The 10k potentio ...
