Chithunzi cha AD9649BCPZ-20 IC ADC 14BIT 32LFCSP

Kufotokozera

The AD9649 ndi monolithic, single channel 1.8 V supply, 14-bit, 20/40/65/80 MSPS analog-to-digital converter (ADC).Imakhala ndi sampuli yogwira ntchito kwambiri-ndi-hold circuit komanso pa-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).Kuyika kwa wotchi yosiyana yokhala ndi magawo 1, 2, kapena 4 omwe amagawaniza amawongolera matembenuzidwe onse amkati.Deta yotulutsa digito imaperekedwa mumitundu yofananira ya binary, imvi, kapena mitundu iwiri yothandizirana.Wotchi yotulutsa data (DCO) imaperekedwa kuti iwonetsetse nthawi yoyenera ya latch ndikulandila malingaliro.Magawo onse a 1.8 V ndi 3.3 V CMOS amathandizidwa.AD9649 ikupezeka mu LFCSP yotsogola 32 ya RoHS ndipo imatchulidwa pa kutentha kwa mafakitale (−40°C mpaka +85°C).
