The LM386 OPAMP is a power amplifier designed for use in low voltage consumer applications. 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 20 to 200. The inputs are ground referenced while the output automatically biases to one-half the supply voltage.The inputs are ground referenced while the output is automaticallybiased to one half the supply voltage. The quiescentpower drain is only 24 milliwatts when operating from a6 volt supply, making the LM386 ideal for battery operation ,
