要：人类是不寻常的生物，因为有时局部知识、自我和放错了位置的信心都没有一个主题的知识比更危险。电子设计，曲解和误解可能会导致无法按预期工作的电路。到一个没有经验的设计师，部分电路看起来他们应该工作。卑躬与此同时，经验丰富的工程师屈膝，不知道怎么有人让自己修理了。此应用程序注礼物三个案例研究，说明了一些简单的分析和正确认识的物理定律如何教育设计师以避免类似问题在未来设计。Maxim>DesignSupport>TechnicalDocuments>ApplicationNotes>A/DandD/AConversion/SamplingCircuits>APP4605Maxim>DesignSupport>TechnicalDocuments>ApplicationNotes>AmplifierandComparatorCircuits>APP4605Maxim>DesignSupport>TechnicalDocuments>ApplicationNotes>CircuitProtection>APP4605Keywords:noise,inexperienced,cleanpower,groundplanes,impedanceDC,levelmatching,powersupply,decouplingcapacitors,analogtodigitalconverters,ADC,DAC,signalprocessing,boardlayout,bounce,radioresonance,antenna,wavelength,partsmisuseMar09,2011APPLICATIONNOTE4605AvoidDesignMisinterpretationsthatPut……

摘要：人类是不寻常的动物，因为有时是局部的知识，自我，和错位的信心比任何一个主题的知识更危险。随着电子设计，曲解和误解可能会导致电路无法如预期般运作。一个没有经验的设计师，一些电路看起来像他们应该工作。同时，经验丰富的的工程师cringes，不知道怎么有人可以得到自己在这样的修复。本应用笔记介绍了三个案例研究，说明一些简单的分析和物理规律的正确认识如何能教育的设计师，以避免类似的问题在未来的设计。Maxim>DesignSupport>TechnicalDocuments>ApplicationNotes>A/DandD/AConversion/SamplingCircuits>APP4605Maxim>DesignSupport>TechnicalDocuments>ApplicationNotes>AmplifierandComparatorCircuits>APP4605Maxim>DesignSupport>TechnicalDocuments>ApplicationNotes>CircuitProtection>APP4605Keywords:noise,inexperienced,cleanpower,groundplanes,impedanceDC,levelmatching,powersupply,decouplingcapacitors,analogtodigitalconverters,ADC,DAC,signalprocessing,boardlayout,bounce,radioresonance,antenna,wavelength,partsmisuseMar09,2011APPLICATIONNOTE4605AvoidDesignMisinterpretationsthatPut……

摘要：电子系统错误通常是模拟的，而不是数字。模拟信号噪声，串扰，非线性问题是容易。本应用笔记讨论了电源和地面的清洁和完整性的需要。模拟接口，可为许多设计的陷阱，这样的例子展示了如何使用现有的IC来克服常见的模拟问题。Maxim>DesignSupport>TechnicalDocuments>Tutorials>GeneralEngineeringTopics>APP4992Maxim>DesignSupport>TechnicalDocuments>Tutorials>Power-SupplyCircuits>APP4992Keywords:noisedecoupling,capacitor,selfresonancestar,groundfilter,RC,LC,resistor,inductor,voltagereference,LDO,LNA,analog,interface,crosstalk,linearity,systemonachip,safety,opamps,groundplanes,power,busses,sensorconditioningMar08,2011TUTORIAL4992ReducetheChancesofHumanError:Part1,PowerandGroundBy:BillLaumeister,StrategicApplicationsEngineerMar08,2011Abstract:Electronicsystemerrorsaretypicallyanalog,notdigital.Analogisproneto……

摘要：一个没有经验的设计师可能会认为，电源去耦电容和理由是每一个坏的噪音吸收魔法，神秘的东西。他们都没有。本应用笔记讨论适当的电容选择。脱钩自身共振点以上的电源总线，它解释了故障电容器。为了说明的力量和地平面，电子比喻电容的特点是使用。电子的行为是可笑的说明。指导向在地面的飞机地面星点的电流通过开槽的平面显示。Maxim>AppNotes>GeneralEngineeringTopicsPrototypingandPC-BoardLayoutKeywords:OpAmps,groundplanes,power,busses,sensorconditioning,reference,decoupling,channelerror,Dec19,2008capacitors,inductors,offset,digital,analog,electrons,brushmotors,noise,sparks,arcing,slot,audio,sensitive,threshold,jitter,ADC,DAC,PGAAPPLICATIONNOTE4345WellGrounded,DigitalIsAnalogBy:BillLaumeisterAbstract:Aninexperienceddesignermaythinkthatpowerdecouplingcapacitorsandgroundsaremagicmysticalthingsthatabsorbeverybadnoise.Theyarenot.Thisapplicationnotediscussespropercapacitorselection.Itexplainsthefailureofcapacitorstodecouplepowerbusesabovetheirself-resonancepoint.Toillustratetheforcesandcha……
