  PDF, 425 Kb, 修订版: B, 档案已发布: Oct 9, 2011
  This glossary is a collection of the definitions of Texas Instruments' Delta-Sigma (О”ОЈ), successive approximation register (SAR), and pipeline analog-to-digital (A/D) converter specifications and performance characteristics. Although there is a considerable amount of detail in this document, the product data sheet for a particular product specification is the best and final reference.

  Interleaving Analog-to-Digital Converters
  PDF, 64 Kb, 档案已发布: Oct 2, 2000
  It is tempting when pushing the limits of analog-to-digital conversion to consider interleaving two or more converters to increase the sample rate. However, such designs must take into consideration several possible sources of error.

  What Designers Should Know About Data Converter Drift
  PDF, 95 Kb, 档案已发布: Oct 2, 2000
  Exactly how inaccurate will a change in temperature make an analog-to-digital or digital-to-analog converter? As designers are well aware, a 12-bit device may provide a much lower accuracy at its operating-temperature extremes, perhaps only to 9 or even 8 bits. But for lack of more precise knowledge, many play it safe (and expensive) and overspecify.
