   LM386 - Low Voltage Audio Power Amplifier







   General Description
   The LM386 is a power amplifier designed for use in low voltage con-
   sumer applications. The gain is internally set to 20 to keep exter-
   nal part count low, but the addition of an external resistor and 
   capacitor between pins 1 and 8 will increase the gain to any value
   up to 200. The inputs are ground referenced while the output is 
   automatically biased to one half the supply voltage. The quiescent
   power drain is only 24 milliwatts when operating from a 6 volt 
   supply, making the LM386 ideal for battery operation.
