  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

  Example Temperature Measurement Applications Using the ADS1247 and ADS1248 (Rev. B)
  PDF, 189 Kb, 修订版: B, 档案已发布: May 9, 2016
  This document discusses the use of the ADS1247 and ADS1248 precision analog-to-digital converters (ADCs) together with a resistive temperature device (RTD) and thermocouple to measure temperature. Included are detailed examples of the most common configurations of a two-wire RTD a three-wire RTD a four-wire RTD and a thermocouple with cold junction compensation.

  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.
