  • AB-174: Getting the Full Potential from your ADC (Rev. A)
    PDF, 72 Kb, Revision: A, Datei veröffentlicht: Jun 28, 2002
    Many of today?s high-resolution ADCs (Analog-to-Digital Converters) are operating from a single supply and use fully differential inputs. This can be a problem for single-ended signals that are bipolar relative to common. This article illustrates circuit configurations that preserve the full-scale input range by using modern features, such as Programmable Gain Amplifiers (PGAs) and internal voltag
  • A Glossary of Analog-to-Digital Specifications and Performance Characteristics (Rev. B)
    PDF, 425 Kb, Revision: B, Datei veröffentlicht: 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.

    The ADS1250, ADS1251, ADS1252, ADS1253 and ADS1254 family of high-resolution analog-to-digital converters (ADCs) share an advanced delta-sigma (О”ОЈ) topology. This application note reviews the frequency characteristics of these devices and shows how to use a companion Microsoft Excel? spreadsheet (sbaa103a.zip), available for download from the TI web site, to calculate the frequency res
  • Digital Filter Types in Delta-Sigma ADCs
    PDF, 219 Kb, Datei veröffentlicht: Jun 27, 2017
    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
