Isekethe entsha neyoqobo ye-LDC1612DNTR Isithombe Esifakiwe

incazelo emfushane:

I-LDC1612 kanye ne-LDC1614 yiziteshi ezingu-2 nezi-4, i-28-bit inductance to digital converters (LDCs) ukuze uthole izixazululo zenzwa yokufundisa.Ngamashaneli amaningi nokusekelwa kokuzwa okukude, i-LDC1612 ne-LDC1614 zinika amandla izinzuzo zokusebenza nokwethembeka kwezinzwa eziguquguqukayo ukuze zitholakale ngezindleko eziphansi namandla.Imikhiqizo kulula ukuyisebenzisa, idinga kuphela ukuthi imvamisa yenzwa ibe phakathi kuka-1 kHz no-10 MHz ukuze iqale ukuzwa.Ibanga elibanzi le-1 kHz ukuya ku-10 MHz lenzwa yenzwa liphinde livumele ukusetshenziswa kwamakhoyili amancane kakhulu e-PCB, kuqhubeke kwehlisa izindleko zesixazululo sezinzwa nosayizi.Amashaneli anokucaca okuphezulu avumela ububanzi benzwa obukhulu kakhulu, obugcina ukusebenza kahle okudlula amadiamitha amakhoyili amabili.Iziteshi ezifaniswa kahle zivumela ukukalwa okuhlukile kanye ne-ratiometric, okwenza abaklami bakwazi ukusebenzisa isiteshi esisodwa ukuze banxephezele inzwa yabo ngezimo zemvelo nokuguga njengezinga lokushisa, umswakama, nokukhukhuleka kwemishini.Njengoba kulula ukuyisebenzisa, amandla aphansi, kanye nezindleko eziphansi zesistimu le mikhiqizo yenza abaklami bakwazi ukuthuthukisa ukusebenza kahle, ukwethembeka, nokuguquguquka ngaphezu kwezixazululo ezikhona zokuzwa kanye nokwethula amakhono enzwa amasha emikhiqizweni kuzo zonke izimakethe, ikakhulukazi izinhlelo zokusebenza zabathengi nezimboni.Lawa madivayisi acushwa kalula ngesixhumi esibonakalayo se-I2C.I-LDC1612 enamashaneli amabili iyatholakala kuphakheji ye-WSON-12 kanti i-LDC1614 eneziteshi ezine iyatholakala kuphakheji ye-WQFN-16.

Isingeniso

Ukutholwa kwedatha (DAQ) kubhekisela ekuqoqweni okuzenzakalelayo kwamasignali angewona amandla noma amandla avela kumayunithi e-analog nawedijithali njengezinzwa namanye amadivaysi azokalwa, futhi athunyelwe kukhompuyutha engusokhaya ukuze ihlaziywe futhi icutshungulwe.Uhlelo lokutholwa kwedatha luwuhlelo lokulinganisa oluguquguqukayo, oluchazwe umsebenzisi oluhlanganisa isofthiwe yokulinganisa nemikhiqizo yezingxenyekazi zekhompuyutha ngokusekelwe kumakhompyutha noma ezinye izinkundla zokuhlola ezikhethekile.

Ukutholwa kwedatha, okwaziwa nangokuthi ukutholwa kwedatha, kuyisixhumi esibonakalayo esisebenzisa idivayisi ukuqoqa idatha kusuka ngaphandle kwesistimu nokuyifaka ngaphakathi kwesistimu.Ubuchwepheshe bokutholwa kwedatha busetshenziswa kakhulu emikhakheni ehlukahlukene.Isibonelo, amakhamera, amamakrofoni, angamathuluzi okuthola idatha.

Idatha eqoqiwe izinhlobonhlobo zamanani aphathekayo aguqulelwe abe amasignali, njengezinga lokushisa, izinga lamanzi, isivinini somoya, ukucindezela, njll., okungaba i-analog noma idijithali.Ukuthola ngokuvamile kuyindlela yesampula, okungukuthi, ukuqoqwa kwedatha endaweni efanayo kuyaphindwa ngezikhathi ezithile (okubizwa ngokuthi imijikelezo yesampula).Idatha eningi eqoqwe ivele ngokushesha, kodwa futhi ingaba inani le-eigenvalue esikhathini esithile.Ukulinganiswa kwedatha okunembile kuyisisekelo sokutholwa kwedatha.Izindlela zokulinganisa idatha ziwukuxhumana nabantu abangathintwa, futhi izici zokuthola zihlukene.Kungakhathalekile ukuthi iyiphi indlela nengxenye, isekelwe ekungathintini isimo sento ehlolwayo kanye nendawo yokulinganisa ukuze kuqinisekiswe ukulunga kwedatha.Ukutholwa kwedatha kunezinhlobonhlobo zemithelela, okuhlanganisa ukutholwa kwenani eliqhubekayo lomzimba lokuphambene.Emdwebeni osizwa ngekhompuyutha, ekudwebeni, nasekuklanyweni, inqubo yokwenza izithombe zibe yidijithali noma izithombe zingaphinde zibizwe ngokuthi ukutholwa kwedatha, lapho kuqoqwa amanani ejiyomethri (noma amanani aphathekayo, njenge-grayscale).

Inhloso

Ukutholwa kwedatha kusho inqubo yokuqoqa ngokuzenzakalelayo ulwazi kumayunithi e-analog nawedijithali ngaphansi kokuhlolwa, njengezinzwa namanye amadivaysi ahlolwayo.Amasistimu wokutholwa kwedatha ayashintshashintsha, amasistimu okulinganisa achazwe umsebenzisi ahlanganisa izingxenyekazi zekhompuyutha zokulinganisa nemikhiqizo yesofthiwe.

Injongo yokutholwa kwedatha ukukala izenzakalo ezibonakalayo ezifana ne-voltage, i-current, izinga lokushisa, ingcindezi, noma umsindo.Ukutholwa kwedatha okusekelwe ku-PC, kukalwa ngenhlanganisela yezingxenyekazi zekhompuyutha zemojuli, isofthiwe yohlelo lokusebenza nekhompyutha.Nakuba amasistimu okutholwa kwedatha anezincazelo ezihlukene kuye ngezidingo zezinhlelo zokusebenza ezihlukene, isistimu ngayinye iyaqoqa, ihlaziye, futhi ibonise ulwazi ngenjongo efanayo.Uhlelo lokutholwa kwedatha luhlanganisa amasignali, izinzwa, ama-actuator, isimo sesignali, okokusebenza kokutholwa kwedatha, nesofthiwe yohlelo lokusebenza.
