Chithunzi cha AD9251BCPZ-65 IC ADC 14BIT 64LFCSP

Kufotokozera

The AD9251 ndi monolithic, wapawiri-channel, 1.8 V supply, 14-bit, 20 MSPS/40 MSPS/65 MSPS/80 MSPS analog-to-digital converter (ADC).Imakhala ndi mawonekedwe apamwamba kwambiri ogwiritsira ntchito-andhold circuit ndi on-chip voltage reference.Chogulitsacho chimagwiritsa ntchito mapangidwe a mapaipi amitundu yosiyanasiyana okhala ndi malingaliro owongolera zolakwika kuti apereke kulondola kwa 14-bit pamitengo ya data ya 80 MSPS ndikutsimikizira kuti palibe ma code omwe akusowa pa kutentha kwathunthu.ADC ili ndi zinthu zingapo zomwe zimapangidwira kuti zizitha kusinthasintha komanso kuchepetsa mtengo wadongosolo, monga mawotchi osinthika ndi masanjidwe a data komanso kupanga mawonekedwe oyeserera a digito.Njira zoyesera za digito zomwe zilipo zikuphatikiza ma deterministic ndi pseudorandom, pamodzi ndi mayesero omwe amafotokozedwa ndi ogwiritsa ntchito omwe adalowetsedwa kudzera pa serial port interface (SPI).Kulowetsa kosiyana kosiyana kumawongolera matembenuzidwe onse amkati.An optional duty cycle stabilizer (DCS) amalipira kusiyanasiyana kwanthawi yantchito ya wotchi ndikusunga magwiridwe antchito abwino kwambiri a ADC.Deta yotulutsa digito imaperekedwa mumitundu yofananira ya binary, imvi, kapena mitundu iwiri yothandizirana.Wotchi yotulutsa data (DCO) imaperekedwa panjira iliyonse ya ADC kuti iwonetsetse nthawi yoyenera ya latch ndikulandila malingaliro.Magawo onse a 1.8 V ndi 3.3 V CMOS amathandizidwa ndipo zotuluka zimatha kuchulukitsidwa pabasi imodzi yotulutsa.AD9251 ikupezeka mu 64-lead RoHS Compliant LFCSP ndipo imatchulidwa pa kutentha kwa mafakitale (−40°C mpaka +85°C).
