 +
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 indexed.
 +
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.  Also note the links at [[Op amp]]

Key Words int the Topic Column:
 +
 +
*OpAmp = well the whole page is op amps so maybe we will delete this sometime later
 +
*Circuit = topic is a specific circuit
 +
*Project = if more of a project than just a circuit, distinction can be vague.
 +
*Tutorial = a discussion of the theory ( of more than just one circuit, or of one circuit in depth ).
 +
 +
Should we add more keywords? -- just put them here
 +
* oscillator = make it wiggle
 +
* amplifier = make it bigger
 +
 +
''"Amplifiers oscillate. Oscillators don't." - unknown''

Latest revision as of 18:00, 29 January 2012

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 indexed. 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. Also note the links at Op amp


Key Words int the Topic Column:

  • OpAmp = well the whole page is op amps so maybe we will delete this sometime later
  • Circuit = topic is a specific circuit
  • Project = if more of a project than just a circuit, distinction can be vague.
  • Tutorial = a discussion of the theory ( of more than just one circuit, or of one circuit in depth ).

Should we add more keywords? -- just put them here

  • oscillator = make it wiggle
  • amplifier = make it bigger

"Amplifiers oscillate. Oscillators don't." - unknown
