Audio Power Amplifier LM386 Semiconductor Datasheet

audio power amplifier wiring diagram datasheet

This is audio power amplifier semiconductor with low voltage electric. In the datasheet equivalent schematic and Connection diagrams attached. This semiconductor can be applied for any low voltage consumer application such as AM-FM radio amplifiers, Portable tape player amplifiers, Intercoms, TV sound systems, Line drivers, Ultrasonic drivers, Small servo drivers, and also Power converters. 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 volt supply, making the LM386 ideal for battery operation. 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 from 20 to 200.
