    RTD Ratiometric Measurements and Filtering Using the ADS1148 and ADS1248
    The ADS1148 and ADS1248 family of devices are highly integrated delta-sigma (О”ОЈ) 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)
    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. This document provides sufficien

    Digital Filter Types in Delta-Sigma ADCs
    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 ADC,which 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)
    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.
