- A Glossary of Analog-to-Digital Specifications and Performance Characteristics (Rev. B)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 ConvertersPDF, 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. - Principles of Data Acquisition and Conversion (Rev. A)PDF, 132 Kb, 修订版: A, 档案已发布: Apr 16, 2015
- What Designers Should Know About Data Converter DriftPDF, 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.
