  • RTD Ratiometric Measurements and Filtering Using the ADS1148 and ADS1248
    PDF, 563 Kb, Datei veröffentlicht: 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
