LM380 is used to produce a phase shift of 180° in the circuit. An RC network of three resistors and capacitors is connected in the feedback path. Each RC element produces a phase shift of my 60°. And together they make a complete 180° phase shift. This is how the phase shift oscillator circuit works. Applications of LM380 Audio Power Amplifier IC:

LM380 is an audio amplifier employed specifically for power audio amplification requirements. It provides a constant internal gain. A particular input signal permits ground reference signal and the out signal keeps its level to the half of the used input voltage. Three ground pins on both sides of the IC generate its use simpler for anybody to make use of it.
