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 up to 200.
biased to one half the supply voltage. The quiescent power drain is
only 24 milliwatts when operating from a 6 volt supply, making the
SL386 ideal for battery operation.
