Signetics Corp. NE5018F - page 550
Datel Systems Inc. or Datel-Intersil ADC856C - page 145
Micro Power Systems (owned by the Exar Corporation) MP7533MP - page ???
??? need to find this. I thought the Datel one with the custom HP number would be hard.
and one more, the MUX
Precision Monolithic Inc. - page 764
These are a fountain of knowledge. Now only specs but app notes and introductions as to why to use them in design. Enjoy.
