Low Voltage Audio Power Amplifier
General Description
The 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 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.
