  • Thermocouple Temperature Measurements Using Isolated Amplifiers (Rev. A)
    PDF, 145 Kb, Revisión: A, Archivo publicado: agosto 11, 2017
    The most common thermocouple in use today is the Type K. A Type-K thermocouple is inexpensive accurate and works reliably in harsh environments. Type-K thermocouples can measure temperatures ranging from –200°C to +1250°C and have a Seebeck coefficient of S = 41 μV/K at room temperature.

    PDF, 563 Kb, Archivo publicado: marzo 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

    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.

    Thermocouples are common temperature sensors used in a wide variety of commercial and industrialapplications. While slightly less accurate than resistance temperature detectors (RTDs) thermocouplescover a wide temperature range are self-powered and have a fast response time. Their simpleconstruction make them inexpensive and durable. Because of the small sensor voltage and low noiserequ

    RTDs or resistance temperature detectors are sensors used to measure temperature. These sensors arethe among the most accurate temperature sensors available covering large temperature ranges.However getting accurate measurements with precision analog-to-digital converters (ADCs) requiresattention to detail in design of measurement circuits and calculation of the measurement.

  • Digital Filter Types in Delta-Sigma ADCs
    PDF, 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
