INTEGRAL IL386D, IL386N Datasheet
Low Voltage Audio Power AMP
The IL386 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
IL386 ideal for battery operation.
