AD9251BCPZ-65 IC ADC 14BIT PIPELINED 64LFCSP

Ibisobanuro

AD9251 ni monolithic, imiyoboro ibiri, 1.8 V itanga, 14-bit, 20 MSPS / 40 MSPS / 65 MSPS / 80 MSPS igereranya-na-ihindura imibare (ADC).Iranga imikorere ihanitse sample-kandi ikomeza umuzenguruko hamwe na chip voltage yerekana.Igicuruzwa gikoresha imiyoboro myinshi itandukanye yububiko hamwe nibisohoka byo gukosora amakosa yo gutanga amakosa yo gutanga 14-bit kuri 80 ya data ya MSPS no kwemeza ko nta code yabuze hejuru yubushyuhe bwuzuye.ADC ikubiyemo ibintu byinshi byashizweho kugirango byoroherezwe guhinduka no kugabanya ibiciro bya sisitemu, nk'isaha ishobora gutegurwa no guhuza amakuru hamwe no gutangiza ibizamini bya sisitemu.Ibizamini bya digitale biboneka harimo ibyubatswe muburyo bwa détinistinistique na pseudorandom, hamwe nibisobanuro byabakoresha-basobanuye ibizamini byinjijwe binyuze kumurongo wimbere (SPI).Itandukaniro ryisaha itandukanye igenzura ibintu byose byimbere.Impinduka zidasanzwe zamahoro (DCS) yishyura ibintu bitandukanye muburyo bwisaha mugihe gikomeza imikorere myiza muri ADC.Ibyasohotse muburyo bwa digitale bitangwa muri offset binary, kode yimyenda, cyangwa ibice bibiri byuzuzanya.Isaha isohoka ryamakuru (DCO) itangwa kuri buri muyoboro wa ADC kugirango harebwe igihe gikwiye hamwe no kwakira logique.Byombi 1.8 V na 3.3 V CMOS urwego rushyigikiwe kandi amakuru asohoka arashobora kugwizwa kuri bisi imwe isohoka.AD9251 iraboneka muri 64-iyobora RoHS Yubahiriza LFCSP kandi isobanurwa hejuru yubushyuhe bwinganda (−40 ° C kugeza + 85 ° C).
