This described work that was undertaken using these amplifiers in analogue computers of the day. Op-amp developmentĪlthough the term operational amplifier has now become totally integrated into today's electronics terminology, it may not be realised that it dates back to a paper published in 1947. One of the advantages of using op amp circuits is that the electronic circuit design is often very easy whilst still yielding high performance finished circuits. As such the operational amplifier is one of the most versatile building blocks available to the analogue electronics circuit design engineer and hobbyist. The operational amplifier can form the basis of a host of other circuits ranging from filters to timers, and oscillators to comparators and astables. Operational amplifier circuit symbol with ICs The op-amp is a differential amplifier and it is a very high performance amplifier circuit block it enables many different electronic amplifier circuits to be designed with the addition of just a handful of other components. Within the analogue electronics arena, none has made more difference than the operational amplifier, or op-amp. Integrated circuits, ICs have made a huge impact on the electronics scene – both analogue and digital circuits have changed the face of electronics. Introduction Op amp gain Bandwidth Op amp slew rate Offset null Input impedance Output impedance Current feedback op amp Understanding specifications How to choose an op amp Op amp circuits summary They are easy to use and can provide some near perfect analogue circuits.
Op-Amp Basics: What is an Operational Amplifier Operational amplifiers are one of the most useful circuit blocks for analog electronic circuit design.
