Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to LM380. LM-380 is an audio amplifier, specially designed for the customer's power audio amplification purposes. Its designers fix its gain internally up to 34dB. In LM 380, ground reference signal is allowed by a unique input stage and the output automatically maintains its level to half of the supplied input voltage. LM-380 has a copper lead frame. The three pins in the middle of the IC on both side, are basically the ground pins. These three pins on both sides makes it easy for the user to use this device for standard PC's. LM 380 has several different features e.g. wide supply voltage range, high peak current, low distortion etc. Moreover, LM 380 provides high input impedance, low quiescent power drain, fixed voltage gain, input referenced to ground etc and a lot more. LM-380 is the most common device and easily available in market now a days due to its cost effectiveness and high performance. LM 380 can be used at different places in real life. Its applications may include intercoms, ultrasonic drivers, line drivers, teaching machine output, television sound systems, alarms, phonograph amplifiers etc. Some other applications include power converters, AM radio, FM radio, servo motor drivers etc. The further detail about LM-380 will be given later in this tutorial.

Introduction to LM380

LM380 is an audio amplifier used specially for power audio amplification purposes. It has a fixed internal gain. A specific input signal allows ground reference signal and the out signal maintains its level to the half of the applied input voltage. Three ground pins on both sides of the IC make its use easier for anyone to use it. wide supply voltage ranges, high peak current, high input impedance, low distortion are its major features. LM-380 can be used in intercoms, servo motors drivers, alarms, TV sound systems etc. LM 380 IC is shown in the figure given below.
