摘要：线性数字电位器，可用于任意电压曲线和波形。为数字电位器的替代名称是一个“字符串”数字-模拟转换器（DAC）。测井盆是线性锅产生对数响应的应用，如音频的艺术。Maxim>AppNotes>A/DandD/AConversion/SamplingCircuitsAudioCircuitsDigitalPotentiometersGeneralEngineeringTopicsKeywords:digitalpots,potentiometer,voltagedivider,sensorconditioning,ratiometric,precisionresistor,Dec11,2008resistance,ratio,singlepowersupply,temperaturecoefficient,lowdrift,linear,log,logarithmic,arbitrarywaveformcurve,stringDAC,audioAPPLICATIONNOTE4346Pots,Pans,Logs,andLinearDigitalPotsCreateArbitraryVoltageCurvesBy:BillLaumeisterAbstract:Lineardigitalpotentiometerscanbeusedtomakearbitraryvoltagecurvesandwaveforms.Analternativenameforadigitalpotisa"string"digital-to-analogconverter(DAC).Loggingpotsistheartofmakingalinearpotproducealogarithmicresponsefora……

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……

摘要：非线性应用，如调整音量控制，音频应用，可以用线性数字电位器（盆）。本文讨论了如何创建一个“pseudologarithmic”抽头数字电位器（锅）。这是通过简单地增加一个单一电阻到数字电位器时，作为一个可变电阻配置。Maxim>Designsupport>Appnotes>AudioCircuits>APP838Maxim>Designsupport>Appnotes>DigitalPotentiometers>APP838Maxim>Designsupport>Appnotes>GeneralEngineeringTopics>APP838Keywords:linearpots,digitalpot,digitalpotentiometer,logpots,logpotentiometers,pseudologpots,pseudologarithmic,potentiometers,audiovolume,volumecontrolApr27,2011APPLICATIONNOTE838UseaLinearPotentiometertoCreateaNonlinearTransferFunctionforAudioVolumeControlAbstract:Lineardigitalpotentiometers(pots)canbeusedinnonlinearapplications,suchasadjustingvolumecontrolinaudioapplications.Thisarticlediscusseshow……
