Application Notes
- RTD Ratiometric Measurements and Filtering Using the ADS1148 and ADS1248PDF, 563 Кб, Файл опубликован: 13 мар 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 Кб, Версия: B, Файл опубликован: 9 май 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.
