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 - A Basic Guide to RTD MeasurementsPDF, 333 Kb, Datei veröffentlicht: Jun 19, 2018
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.

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
