LM386 IC is a popular low voltage power amplifier used mostly in consumer applications including: AM-FM Radio Amplifiers, line drivers, small servo drivers, power converters, TV sound systems and more. The LM386 IC operates from 4V to 15V, has a good adjustable gain value from 20 to 200 with the use of external resistors and capacitors. It can well drive loads from 4W to 32W . This IC is easy to use and integrate in your audio amplifier circuits.
