OpAmp Links

Many of these circuits come in several different variations, many of which are lumped together here. Some circuits are explained, other just have schematics ( sometimes without even component values. There are many op amp circuits not included here. Even in the referenced document not all circuits are indexec These are not projects, but rather building blocks useful in project work. Many of these links are PDF files, this should be noted at the beginning of the link description. Many of the links contain multiple topics ( often under slightly different titles ) you may need to search through the references a bit. There are also many different types of op amps, transconductance, video .... Most of these links are for general purpose op amps.
