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, Revisión: B, Archivo publicado: 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, Archivo publicado: marzo 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.

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 ADCsPDF, 219 Kb, Archivo publicado: 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 - Principles of Data Acquisition and Conversion (Rev.
