Operational amplifiers (op amps, op-amps) are general-purpose, closed-loop devices that are used to implement linear functions. They compare two incoming signals and release a third signal that is an ...

The operational amplifier is arguably the most useful single device in analog electronic circuitry. When you apply them in the circuits, you must know their basics and functions. As for the function ...

Are your jellybeans getting stale? [lcamtuf] thinks so, and his guide to choosing op-amps makes a good case for rethinking what parts you should keep in stock. For readers of a certain vintage, the ...

This application note discusses a variety of M.S. Kennedy’s operational amplifiers (op amps). It covers the absolute maximum ratings and safe operating area of operational amplifiers, and a brief ...

Operational transconductance amplifiers (OTA) are devices that convert an input voltage to an output current. They are primarily voltage-to-current amplifiers. Unlike traditional operational ...
