DESCRIPTION
ADS62P15isadualchannel11-bitA/Dconverterwithmaximumsampleratesupto125MSPS.Itcombineshigh
performanceandlowpowerconsumptioninacompact64QFNpackage.Usinganinternalsampleandholdand
lowjitterclockbuffer,theADCsupportshighSNRandhighSFDRathighinputfrequencies.Ithascoarseand
finegainoptionsthatcanbeusedtoimproveSFDRperformanceatlowerfull-scaleinputranges.
ADS62P15includesadigitalprocessingblockthatconsistsofseveralusefulandcommonlyuseddigital
functionssuchasADCoffsetcorrection,finegaincorrection(instepsof0.05dB),decimationby2,4,8and
in-builtandcustomprogrammablefilters.Bydefault,thedigitalprocessingblockisbypassed,anditsfunctions
aredisabled.
Twooutputinterfaceoptionsexist–parallelCMOSandDDRLVDS(DoubleDataRate).ADS62P15includes

Nevertheless,thedevicecanalsobedrivenwithanexternalreference.Thedeviceisspecifiedovertheindustrial
temperaturerange(–40°Cto85°C).
