RTD Ratiometric Measurements and Filtering Using the ADS1148 and ADS1248
PDF, 563 Kb, 档案已发布: Mar 13, 2013
The ADS1148 and ADS1248 family of devices are highly integrated delta-sigma (ΔΣ) converters that areoptimized for the measurement of temperature sensors including resistance temperature detectors(RTDs) thermocouples and thermistors. In a typical RTD measurement application the ADS1148 andADS1248 are configured in a ratiometric topology using the built-in IDAC current sources feeding thro

Digital Filter Types in Delta-Sigma ADCs
PDF, 219 Kb, 档案已发布: 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

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.
