- Thermocouple Temperature Measurements Using Isolated Amplifiers (Rev. A)PDF, 145 Kb, 修订版: A, 档案已发布: 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. - Low-Cost Single-Chip Diff Temp Measurement Solution Using Delta-Sigma ADCs (Rev.

- RTD Ratiometric Measurements and Filtering Using the ADS1148 and ADS1248PDF, 563 Kb, 档案已发布: Mar 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 - Example Temperature Measurement Applications Using the ADS1247 and ADS1248 (Rev. B)PDF, 189 Kb, 修订版: B, 档案已发布: May 9, 2016
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 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 - Analog-to-Digital Converter Grounding Practices Affect System Performance (Rev.
