LM386 voice audio power amplifier circuit design project


Posted on Feb 5, 2014

Using LM386 power amplifier designed for use in low voltage consumer applications can be designed a very simple voice amplifier with variable gain and volume control. The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value from
