LM301 Improved Op-Amp

Contents hide

LM301 is a general purpose operational amplifiers that feature improved performance over industry standards like the LM709. The IC offers many features which make its application nearly foolproof: Overload protection on the input and output, no latch-up when the common mode range is exceeded, and freedom from oscillations and compensation with a single 30 pF Capacitor. It has advantages over internally compensated amplifiers in that the frequency compensation can be tailored to the particular application.

Operational Amplifier

Operational amplifiers are simple electronic circuits that can boost a weak signal to a level of higher amplitude. An operational amplifier is generally used in applications such as home entertainment systems, megaphones, speakers, and microphones, etc. An op-amp usually operates with a number of feedback components that determine the resulting function or “operation” of the amplifier, by virtue of the different feedback configurations whether resistive, capacitive, or both.
