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 - 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 .

Op amp or Operational Amplifier - Electrical4U
2012年2月24日 · Op Amp Definition: An op amp (operational amplifier) is defined as a DC-coupled voltage amplifier with a high voltage gain used in various electronic circuits. Working Principle: The op amp amplifies the difference between two input signals, known as the differential input voltage, in its open loop operation.
- The Operational Amplifier (op amp) was invented in the 40’s. Bell Labs filed a patent in 1941 and many consider the first practical op amp to be the vacuum tube K2-W invented in 1952 by George Philbrick. - Texas Instruments invented the integrated circuit in 1958 which paved the way for Bob Widlar at Fairchild inventing the uA702 solid state
Operational Amplifier Basics – Types and Characteristics in Detail ...
The op amp, which is the brain, receives analog signals from the eyes, ears, nose, skin, tongue, and other sensors, converts them into various types of signals, and processes them. Sometimes it even emits voice from its mouth (speakers) or moves its arms and legs (motors). Thus, op amps can process various signals in various ways and output them.
