The UTC LM386 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 pin 1 and pin 8 will increase the
gain to any value up from 20 to 200.
The inputs are ground referenced while the output
automatically biases to one-half the supply voltage.The quiescent
power drain is only 24 milliwatts when operating from a 6 voltage
supply, making the LM386 ideal for battery operation.
