- Example Temperature Measurement Applications Using the ADS1247 and ADS1248 (Rev. B)PDF, 189 Kb, Revision: B, Datei veröffentlicht: 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.
