I-One Spot DS90UB936TRGZTQ1 48-VQFN-EP 7×7 isekethe ehlanganisiwe 12-BIT 100MHFPD-LINK III DESERIA

1.Amasekhethi ahlanganisiwe angahlukaniswa ngezindlela eziningi, ngokuya ngokuthi isekethe iyi-analog noma idijithali: amasekhethi ahlanganisiwe e-analog, amasekhethi adidiyelwe edijithali, namasekhethi ahlanganisiwe anesignali ehlanganisiwe (i-analog nedijithali ku-chip eyodwa).
Amasekhethi ahlanganisiwe edijithali angaqukatha noma yini kusukela ezinkulungwaneni kuya ezigidini zamasango anengqondo, ama-flip-flops, ama-multi-taskers, namanye amasekhethi kumamilimitha-skwele ambalwa.Ubukhulu obuncane bale mijikelezo buvumela isivinini esikhulu, ukusetshenziswa kwamandla okuphansi (bona idizayini yamandla aphansi), nokunciphisa izindleko zokukhiqiza uma kuqhathaniswa nokuhlanganiswa kwezinga lebhodi.Lawa ma-IC edijithali, amelwe ama-microprocessors, amaphrosesa wesignali yedijithali, nama-microcontroller, asebenza ngamasignali kanambambili, acubungula u-1 no-0.
I-analogue ICs, ngokwesibonelo, inezinzwa, amasekhethi okulawula amandla, nama-op-amps, acubungula amasignali e-analog.Imisebenzi yokukhulisa, ukuhlunga, ukudilizwa, ukuxuba, njll. iyaqedwa.Ngokusebenzisa amasekhethi ahlanganisiwe e-analogi aklanywe ngobungcweti, anezimpawu ezinhle, umklami wesekethe uyakhululeka emthwalweni wokudizayina yonke into kusukela kokuyisisekelo, i-transistor eyodwa ngesikhathi.
Amasekhethi ahlanganisiwe angahlanganisa amasekhethi e-analog nedijithali ku-chip eyodwa ukuze enze amadivayisi afana neziguquli ze-analog-to-digital kanye neziguquli zedijithali-kuya-analog.Izifunda ezinjalo zinikeza amasayizi amancane nezindleko eziphansi, kodwa kufanele kuqashelwe mayelana nokungqubuzana kwesignali.
2.Ama-chips ngokuvamile aqanjwa kanje: incwadi + inombolo + incwadi
Incwadi yokuqala isifinyezo somkhiqizi we-chip noma uchungechunge lwe-chip.Isibonelo, iningi lalawo aqala nge-MC avela kwa-Motorola futhi iningi lalawo aqala ngo-MAX avela ku-Maxis.
Inombolo emaphakathi iyimodeli yokusebenza.Njenge-MC7805 ne-LM7805, kusukela ku-7805 ungabona ukuthi umsebenzi wabo ukukhipha i-5V, hhayi nje umenzi ofanayo.
Izinhlamvu ezingemuva ziwulwazi lwephakheji, kufanele ubheke imininingwane enikezwe umenzi ukuze wazi kahle ukuthi izinhlamvu zimele liphi iphakethe.
Uchungechunge lwe-74 yigama elivamile lamadivayisi anengqondo e-TTL ajwayelekile, afana ne-74LS00, 74LS02, njll. Akucaci ku-74 kuphela ukuthi uyini umkhiqizo wenkampani.Izinkampani ezihlukene zizongeza iziqalo phambi kwe-74, isb SN74LS00, njll.
3.Inombolo yemodeli ye-IC ephelele kufanele iqukathe okungenani izingxenye ezine ezilandelayo:
Isiqalo (ilebula yokuqala) ----- siwuphawu oluhle lomkhiqizo wenkampani.
Igama ledivayisi ---- ngokuvamile lithinta umsebenzi womkhiqizo (inkumbulo itshela umthamo).
Isigaba samazinga okushisa ----- sihlukanisa phakathi kwebanga lezentengiso, izinga lezimboni, izinga lezempi, njll. Ngokuvamile, u-C ubonisa izinga labantu, ngibonisa izinga lezimboni, u-E ubonisa ibanga lezimboni, u-A ubonisa ibanga le-aerospace kanti uM ubonisa ibanga lezempi. .
Iphakheji ---- libonisa iphakheji kanye nenombolo yezikhonkwane zomkhiqizo.Amanye amamodeli e-IC azoba nokunye okuqukethwe:
Izinga ---- njengememori, i-MCU, i-DSP, i-FPGA, njll. imikhiqizo inomehluko wezilinganiso, njengokuthi -5, -6, nezinye izinombolo ezibonisayo.
Isakhiwo senqubo ---- isb. injongo evamile ama-IC edijithali ama-COMS kanye ne-TL, ngokuvamile aboniswa ngezinhlamvu u-C kanye no-T.
Ukuthi ihambisana nemvelo ----- ngokuvamile inohlamvu ekupheleni kwenombolo yemodeli ukuze ibonise ukuthi ingabe ihambisana nemvelo, njengokuthi z, R, +, njll.
Ukupakisha ----- kubonisa ukuthi hlobo luni lokupakisha impahla ethunyelwayo, isb. ishubhu, i-T/R, isitimela, ithreyi, njll.
Inombolo yenguqulo ---- ibonisa inani lezikhathi lapho umkhiqizo ulungiswe khona, ngokuvamile ngo-M njengenguqulo yokuqala.
