摘要：在一些电子系统，将有助于在输入电压直流偏置输出一个重要的错误。在高增益配置，这是特别真实。偏移调整电路，可添加到“空”出来的偏移电压，高增益的阶段，甚至与实际运放电路中重要的输入失调电压。Maxim>AppNotes>AmplifierandComparatorCircuitsDigitalPotentiometersKeywords:offsetadjust,offsetadjustment,opamp,nullingcircuits,nullingopamps,DCoffsetvoltage,Sep17,2001opampsAPPLICATIONNOTE803EPOTApplications:OffsetAdjustmentinOp-AmpCircuitsAbstract:Insomeelectronicsystems,aDCoffsetvoltageattheinputswillcontributeasignificanterrortotheoutput.Thisisespeciallytrueinhighgainconfigurations.Anoffsetadjustmentcircuitcanbeaddedto"null"outtheoffsetvoltage,makinghighgainstagespracticalevenwithsignificantinputoffsetvoltagesfoundinopampcircuits.ElectronicPotentiometers(EPOTS)offerdesignerstheopportunitytocontrolaresistanceviaadigitalinterfaceandcanbeusedinplaceofmechanical……

摘要：数字电位器（盆）提供音频音量（增益）控制应用的优势，可以取代笨重的机械电位器，尤其是在手持便携设备，如MP3播放器，掌上电脑，手机，移动互联网设备，或立体声调幅/调频收音机。本文档介绍了音频控制，如对数锥盆（日志盆）提供的数字电位器的类型。它会检查使用日志锥盆和音频放大器的几种常见的设计，评估他们的优点和缺点，并建议电路设计。Maxim>AppNotes>AudioCircuitsDigitalPotentiometersKeywords:digitalpot,digitalpotentiometer,audiovolumecontrol,MAX5407,MAX5408,MAX5409,MAX5410,MAX5411,volumecontrol,Dec26,2002volumeadjust,digitalvolumeadjustment,logpots,digitallogpots,logarithmictaper,logarithmic,potentiometersAPPLICATIONNOTE1828AudioGainControlUsingDigitalPotentiometersAbstract:Digitalpotentiometers(pots)offeradvantagesforaudiovolume(gain)controlapplicationsandcanreplacebulkymechanicalpots,especiallyinhandheldportabledevicessuchasMP3players,PDAs,cellphones,mobileInternetdevices,orstereoAM/FMradios.Thisdocumentdescribesthetypesofdigitalpotsavailableforaudiocontrolsuchaslogarithmictaperpots(logpots).Itexaminessev……
