  While in the process of reviewing Texas Instruments applications notes including those from Burr-Brown - I uncovered a couple of treasures this handbook on op amp applications and one on active RC networks. These old publications from 1963 and 1966 respectively are some of the finest works on op amp theory that I have ever seen. Nevertheless they contain some material that is hopelessly outd

  AN-262 Applying Dual and Quad FET Op Amps (Rev. B)
  PDF, 1.1 Mb, Revision: B, File published: May 6, 2013
  The availability of dual and quad packaged FET op amps offers the designer all the traditional capabilitiesof FET op amps including low bias current and speed and some additional advantages. The cost-peramplifieris lower because of reduced package costs. This means that more amplifiers are available toimplement a function at a given cost making design easier. At the same time the availab

  AN-256 Circuitry for Inexpensive Relative Humidity Measurement (Rev. B)
  PDF, 262 Kb, Revision: B, File published: May 6, 2013
  Of all common environmental parameters humidity is perhaps the least understood and most difficult tomeasure. The most common electronic humidity detection methods albeit highly accurate are not obviousand tend to be expensive and complex (See Box). Accurate humidity measurement is vital to a number ofdiverse areas including food processing paper and lumber production pollution monitor
