补偿理想因子与热感二极管系列电阻差异

摘要：当使用外部的热敏二极管测量温度，温度测量的精度上取决于外部二极管的特性。两个关键的参数会影响测量精度是理想因子和系列电阻。本应用指南对远程温度传感器测量结果解释这些参数的影响，并讨论了如何确定补偿及其影响因素。Maxim>AppNotes>AutomotiveTemperatureSensorsandThermalManagementKeywords:temperaturesensor,ideality,thermaldiode,thermalsensediodes,tempsensor,remotetempsensor,sensors,thermal,Sep05,2002temperatuer,temperatureAPPLICATIONNOTE1057CompensatingforIdealityFactorandSeriesResistanceDifferencesbetweenThermal-SenseDiodesAbstract:Whenusinganexternalthermaldiodetomeasuretemperature,theaccuracyofthetemperaturemeasurementdependsonthecharacteristicsoftheexternaldiode.Twocriticalparametersthataffectmeasurementaccuracyareidealityfactorandseriesresistance.Thisapplicationnoteexplainstheeffectsoftheseparametersonremotetemperature-sensormeasurementsanddiscusseshowtodeterminecompensationfactorsfortheir
