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 ).
+
Many of these circuits come in several different variations
−
There are many op amp circuits not included here.
+
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''
