LM3403 Quad Operational Amplifier

Contents hide

LM3403 comprises of four industry standard, high gain, frequency compensated, general purpose amplifiers for cost sensitive equipment. The op-amp is stable at unity gain and does not have a reverse phase in overdrive conditions. The IC is available in a 14-pin hermetically sealed dual in line IC packaging (DIP).

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 and by virtue of the different feedback, configurations whether resistive, capacitive, or both.
