    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

    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.

    Interleaving Analog-to-Digital Converters
    It is tempting when pushing the limits of analog-to-digital conversion to consider interleaving two or more converters to increase the sample rate. However, such designs must take into consideration several possible sources of error.

    What Designers Should Know About Data Converter Drift
    Exactly how inaccurate will a change in temperature make an analog-to-digital or digital-to-analog converter? As designers are well aware, a 12-bit device may provide a much lower accuracy at its operating-temperature extremes, perhaps only to 9 or even 8 bits. But for lack of more precise knowledge, many play it safe (and expensive) and overspecify.
