AD9251BCPZ-65 IC ADC 14BIT PIPELINE 64LFCSP

Inkcazo

I-AD9251 yi-monolithic, i-double-channel, i-1.8 V yokubonelela, i-14-bit, i-20 MSPS/40 MSPS/65 MSPS/80 MSPS i-analog-to-digital converter (ADC).Ibonisa ukusebenza okuphezulu kwesampulu-isekethe kunye nereferensi yombane we-chip.Imveliso isebenzisa ulwakhiwo lwemibhobho yolwahlulo olunezigaba ezininzi ezinengqiqo yolungiso lwemposiso yesiphumo ukunika ukuchaneka kwebhithi ye-14 kumazinga edatha ye-MSPS angama-80 kunye nokuqinisekisa ukuba akukho khowudi zingekhoyo kuluhlu olupheleleyo lobushushu bokusebenza.I-ADC iqulethe iinkalo ezininzi ezenzelwe ukwandisa ukuguquguquka kunye nokunciphisa iindleko zenkqubo, ezifana newotshi ecwangcisiweyo kunye nokulungelelaniswa kwedatha kunye nokuveliswa kwepateni yovavanyo lwedijithali.Iipateni ezikhoyo zovavanyo lwedijithali ziquka eyakhelwe-ngaphakathi iipateni zokumisela kunye nobuxoki, kunye neepatheni zovavanyo ezichazwe ngumsebenzisi ezingenwe ngojongano lwesiriyali sezibuko (SPI).Ungeniso lwewotshi eyahlukileyo lulawula yonke imijikelo yangaphakathi yoguqulo.I-optional duty cycle stabilizer (DCS) ihlawulela ukwahluka okubanzi kumjikelo womsebenzi wewotshi ngelixa igcina ukusebenza okugqwesileyo kukonke kwe-ADC.Idatha yemveliso yedijithali inikezelwe kwi-offset yokubini, ikhowudi engwevu, okanye ifomathi yokuncedisana ngababini.Iwotshi yokukhupha idatha (i-DCO) inikezelwe kwitshaneli nganye ye-ADC ukuze kuqinisekiswe ixesha elifanelekileyo lokuvala ngokufumana ingqiqo.Zombini i-1.8 V kunye ne-3.3 V amanqanaba e-CMOS axhaswa kwaye idatha yemveliso inokuphinda iphindwe kwibhasi enye yokuphuma.I-AD9251 ifumaneka kwi-64-lead RoHS Compliant LFCSP kwaye icaciswe kuluhlu lobushushu beshishini (−40°C ukuya +85°C).
