负载电源监视器可以提高高边电流测量

倍增器，MAX4211显示可以方便地测量功率消散在负载。一个乘数输入连接到负载电压和其他内部模拟负载电流的——就是成比例的电压产生的内部电流检测放大器。乘数输出（VLIL），然后是负载功率成正比的电压。Maxim>AppNotes>AmplifierandComparatorCircuitsKeywords:high-sidecurrent-senseamplifiers,analogvoltagemultipliers,load-powermonitors,A/Dconverters,voltagereferencesNov08,2010APPLICATIONNOTE4507Load-PowerMonitorImprovesHigh-SideCurrentMeasurementsBy:MaurizioGavardoniAbstract:Combiningahigh-sidecurrent-senseamplifierwithananalogvoltagemultiplier,MAX4211showncaneasilymeasurethepowerdissipatedinaload.Onemultiplierinputconnectstotheloadvoltage,andtheothertoaninternalanalogoftheloadcurrent―thatis,aproportionalvoltageproducedbytheinternalcurrent-senseamplifier.Themultiplieroutput(VLIL)isthenavoltageproportionaltoloadpower.AsimilarversionofthisarticleappearedintheAugust1,2008issue
