♠ Incazelo Yomkhiqizo
I-AD7734 iwukunemba okuphezulu, isiphetho esiphezulu se-analog yokuphuma phambili. Ukulungiswa kweqiniso kwe-16-bit pp kuyafezeka ngesikhathi sokuguqulwa esiphelele esingu-500 μs (ukushintsha kwesiteshi okungu-2 kHz), okuyenza ifanelekele izinhlelo zokusebenza zokuphindaphinda ezinesinqumo esiphezulu.
Idivayisi ingalungiswa kusetshenziswa isixhumi esibonakalayo esilula sedijithali, esivumela abasebenzisi ukuthi balinganisele ukusebenza komsindo ngokumelene nokuphuma kwedatha kufika ku-15.4 kHz.
Indawo engaphambili ye-analogi ihlanganisa amashaneli amane okokufaka anesiphetho esisodwa anebanga le-unipolar noma leqiniso le-bipolar ukuya ku-±10 V ngenkathi isebenza kusuka kokunikezwayo kwe-analog eyodwa engu-+5 V. Idivayisi inamandla okuthola ububanzi nobubanzi obungaphansi futhi yamukela ugesi we-analogi ku-±16.5 V ngaphandle kokululaza ukusebenza kwamashaneli aseduze.
Okokufaka kwereferensi komehluko kuhlanganisa ikhono lokubona "No-Reference". I-ADC futhi isekela izinketho zokulinganisa uhlelo lwesiteshi ngasinye. I-digital serial interface ingalungiselelwa ukusebenza kwezintambo ezi-3 futhi ihambisana nama-microcontrollers kanye namaphrosesa esignali yedijithali. Konke okokufaka kwesixhumi esibonakalayo kuqalisiwe i-Schmitt.
Idivayisi icaciswe ukuthi isebenze ebangeni lokushisa elinwetshiwe lasezimbonini elingu--40°C kuya ku-+105°C.
Amanye amadivaysi emndenini we-AD7734 yi-AD7732 kanye ne-AD7738.
I-AD7732 ifana ne-AD7734, kodwa isiphetho sayo sangaphambili se-analog sineziteshi zokufaka ezimbili ezihluke ngokuphelele.
I-AD7738 front end ye-analog iyalungiseka eziteshini ezine ezihlukene ngokuphelele noma eziyisishiyagalombili ezinesiphelo esisodwa, ihlanganisa u-0.625 V kuya ku-2.5 V ububanzi bokufaka kwe-bipolar/unipolar, futhi yamukela i-voltage yokufaka yemodi evamile ukusuka ku-200 mV ukuya ku-AVDD - 300mV.
Okuphumayo kwe-AD7738 multiplexer kuphiniwe ngaphandle, okuvumela umsebenzisi ukuthi asebenzise inzuzo ehlelekayo noma isimo sesignali ngaphambi kokusetshenziswa ku-ADC.
