摘要：为了减少功耗，单电源运算放大器驱动以地为参考的负载，连接一个上拉电阻，输出和正电源电压之间的负载电阻值等于。这除了使运算放大器工作在更高的环境温度和驱动低电阻负载，仅由输出电压和电流（而不是封装的功耗），其最大额定值的限制。Maxim>AppNotes>AMPLIFIERANDCOMPARATORCIRCUITSKeywords:singlesupply,opamp,opamp,applicationcircuit,appnote,appnote,opamps,opamps,tutorial,Feb07,2003tutorialsAPPLICATIONNOTE1877OneResistorTakesHeatfromSingle-SupplyOpAmpsAbstract:Tominimizethepowerdissipationinasingle-supplyopamp,drivingaground-referencedload,connectapullupresistor,withvalueequaltotheloadresistorbetweentheoutputandthepositivesupplyvoltage.Thisadditionenablestheopamptooperateathigherambienttemperaturesanddrivelower-resistanceloads,limitedonlybyitsmaximumratingsforoutputvoltageandcurrent(ratherthanthepackagepowerdissipation).Tomaximizesignalswing,theoutputofasingle-supplyopampisusuallybiasedathalfthe……
