Application Notes

  • Understanding Operational Amplifier Specifications
    PDF, 273 Kb, File published: Jul 13, 1998
    Selecting the right operational amplifier for a specific application requires you to have your design goals clearly in mind along with a firm understanding of what the published specifications mean. This paper addresses the issue of understanding data sheet specifications.This paper begins with background information. First introductory topics on the basic principles of amplifiers are presen
  • Handbook of Operational Amplifier Applications (Rev. B)
    PDF, 2.8 Mb, Revision: B, File published: Sep 19, 2016
    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-301 Signal Conditioning for Sophisticated Transducers (Rev. B)
    PDF, 1.2 Mb, Revision: B, File published: May 6, 2013
    This application note discusses signal conditioning and applications information for a diverse group ofsophisticated and unusual transducers.
  • 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-263 Sine Wave Generation Techniques (Rev. C)
    PDF, 747 Kb, Revision: C, File published: Apr 22, 2013
    This application note describes the sine wave generation techniques to control frequency amplitude anddistortion levels.
  • 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
