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, lo ...
