I-AD9251BCPZ-65 IC ADC 14BIT PIPHIPHI 64LFCSP

Incazelo

I-AD9251 iyi-monolithic, i-dual-channel, i-1.8 V supply, 14-bit, 20 MSPS/40 MSPS/65 MSPS/80 MSPS i-analog-to-digital converter (ADC).Ifaka isampula yokusebenza okuphezulu kwesekethe ye-andhold kanye nereferensi ye-on-chip voltage.Umkhiqizo usebenzisa ukwakheka kwephayiphi okuhlukile kwezigaba eziningi okunengqondo yokulungisa iphutha lokukhiphayo ukuze unikeze ngokunemba kwebhithi-14 kumazinga wedatha angu-80 we-MSPS kanye nokuqinisekisa ukuthi awekho amakhodi angekho ebangeni lokushisa eligcwele lokusebenza.I-ADC iqukethe izici ezimbalwa eziklanyelwe ukukhulisa ukuguquguquka nokunciphisa izindleko zesistimu, njengewashi elihlelekayo nokuqondanisa kwedatha nokwenziwa kwephethini yokuhlola yedijithali ehlelekayo.Amaphethini okuhlola edijithali atholakalayo ahlanganisa amaphethini akhelwe ngaphakathi e-deterministic nawe-pseudorandom, kanye namaphethini okuhlola achazwe ngokwezifiso afakwe nge-serial port interface (SPI).Okokufaka kwewashi okuhlukile kulawula yonke imijikelezo yangaphakathi yokuguqulwa.I-optional duty cycle stabilizer (DCS) inxephezela ukuhluka okubanzi kumjikelezo wewashi kuyilapho igcina ukusebenza okuhle kakhulu kukonke kwe-ADC.Idatha yokuphuma kwedijithali yethulwa ngefomethi ye-offset kanambambili, empunga, noma ngefomethi ehambisanayo yokubili.Iwashi lokuphuma kwedatha (i-DCO) linikezwe isiteshi se-ADC ngasinye ukuze kuqinisekiswe isikhathi esifanele sokuvala ngombono wokwamukela.Womabili amazinga e-1.8 V kanye ne-3.3 V CMOS ayasekelwa futhi idatha yokuphumayo ingaphindaphindwa ebhasini elilodwa eliphumayo.I-AD9251 iyatholakala nge-RoHS Compliant LFCSP eholayo engu-64 futhi icaciswe phezu kwebanga lokushisa lezimboni (−40°C kuya +85°C).
