Operational Amplifier Basics - Op-amp tutorial
An Operational Amplifier, or Op-amp for short, is fundamentally a voltage amplifying device designed to be used with external feedback components such as resistors and capacitors between its output and input terminals.
Operational Amplifier Summary, Op-amp basics
• The Operational Amplifier, or Op-amp as it is most commonly called, can be an ideal amplifier with infinite Gain and Bandwidth when used in the Open-loop mode with typical DC gains of well over 100,000 or 100dB. • The basic Op-amp construction is of a 3-terminal device, with 2-inputs and 1-output, (excluding power connections). • An ...
Operational amplifier - Wikipedia
An operational amplifier (often op amp or opamp) is a DC-coupled electronic voltage amplifier with a differential input, a (usually) single-ended output, [1] and an extremely high gain. Its name comes from its original use of performing mathematical operations in analog computers.
