I-AD9649BCPZ-20 IC ADC 14BIT PIPIPHINDE 32LFCSP

Incazelo

I-AD9649 ingumthombo we-monolithic, wesiteshi esisodwa esingu-1.8 V, i-14-bit, 20/40/65/80 MSPS i-analog-to-digital converter (ADC).Ifaka isekethe yokusebenza okuphezulu kwesampula nokubamba 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 okunokuzikhethela kwezilinganiso zokuhlukanisa okungu-1, 2, noma 4 kulawula yonke imijikelezo yokuguqulwa yangaphakathi.Idatha yokuphuma kwedijithali yethulwa ngefomethi ye-offset kanambambili, empunga, noma ngefomethi ehambisanayo yokubili.Iwashi lokuphuma kwedatha (i-DCO) linikeziwe ukuze kuqinisekiswe isikhathi esifanele sokuvala ngokwamukela okunengqondo.Womabili amazinga e-1.8 V kanye ne-3.3 V CMOS ayasekelwa.I-AD9649 iyatholakala nge-LFCSP ehambisana ne-RoHS engu-32 eholayo futhi icaciswe phezu kwebanga lokushisa lezimboni (−40°C kuya +85°C).
