- 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. - Interfacing the ADS1251/52 to the MSP430PDF, 264 Kb, 档案已发布: Mar 8, 2005
This application report demonstrates an effective method to interface the ADS1251 and ADS1252 sigma-delta data converters to the MSP430F449 microcontroller. The software for this application report was developed on the HPA449 development system. - A Spreadsheet for Calculating the Frequency Response of the ADS1250-54 (Rev.

This application report discusses digital filters which are a ubiquitous feature in delta-sigma analog todigital converters (ADCs). Digital low-pass filters are essential to the functionality of a delta-sigma ADCwhich relies on oversampling and noise shaping to push quantization noise out of band. There arevariations between the types of digital filters used in delta-sigma ADCs that provide - Principles of Data Acquisition and Conversion (Rev. A)PDF, 132 Kb, 修订版: A, 档案已发布: Apr 16, 2015
