    Thermocouple Temperature Measurements Using Isolated Amplifiers (Rev. A)
    PDF, 145 Kb, Revision: A, Datei veröffentlicht: Aug 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.

    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

    Digital Filter Types in Delta-Sigma ADCs
    PDF, 219 Kb, Datei veröffentlicht: 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
