Ukuphikiswa kwe-chip kusetshenziswa kabanzi kunjiniyela wanamuhla kagesi.
Ziyi-analogue ephelele yokumelana okujwayelekile kokukhipha, kepha yiba nenzuzo ebalulekile - usayizi. Isebenzisa la madivayisi akuvumela ukuthi wakhe i-computising yesimanje nenqubo yomsakazo-elekthronikhi.
Zisebenza kubuchwepheshe be-SMT, elibonakala ngokuzenzakalela okuphezulu kokufakwa kwamabhodi wesifunda aphrintiwe.
Ukwakha abamelana ne-chip, sebenzisa ubuchwepheshe obuncanyana noma ubuchwephesha obucwebezelayo, futhi amadivayisi ngokwawo anamazinga ahlukile wephutha lokumelana. Amanani ajwayelekile kakhulu angama-5% noma 1%, futhi anembe kakhudlwana nge-0.01%.
Zisetshenziswa emishini yezokwelapha nangokulinganisa, ama-elekthronikhi wezimoto nawathengi, amadivaysi ahlukahlukene wokuxhumana, ama-Power Supplies, neminye imishini. Kunenombolo enkulu yamadivayisi ngezinhloso ezahlukahlukene, phakathi kwazo:
- Tolstopnoe;
- i-low-voltage esetshenziselwa ukunquma amabutho akhona;
- Ifilimu elinembile ngezimpawu ezinzile;
- Iyakhuthaza;
- okuguquguqukayo;
- Umhlangano;
- Ukukhishwa kwamandla kagesi ngokweqile.
Izici Ukumaka Ukumelana Kwe-Chip
Ukuhamba nge-assortment eyethulwe yabaphikisi be-chip, kuyadingeka ukubheka ukumaka kwabo. Cishe bonke abaphikisi, ngaphandle kosayizi abangama-0402, bamakwe.
Amadivaysi amancane awanayo ilebula, ngoba amane nje ayikho indawo lapho kungenzeka khona ukuyibeka. Uma usayizi weqa i-08005, ukulebula kufakwa ku-resistor, okuqukethe amadijithi amathathu.
Kuyaziwa ukuthi abaphikisayo be-chip ngokubekezelelana ngo-10%, 5%, kanye no-2% abhalwe amadijithi amathathu okuqala. Inombolo ngayinye inencazelo eqinile. Inombolo yokugcina ebhalwe ukumaka ikhombisa inombolo ye-OMMS.
Kanti izinombolo ezimbili zokuqala ziveza uMantissa. Ukuqoka iphuzu ledesimali, kwesinye isikhathi incwadi R. ingezwa izinombolo ezinenjongo. Kuvela ukuthi ukumaka ama-242 kubonisa i-tomanal 24x102 ohm, futhi lokhu kungu-2.4 com.
Kuya ekubekezelelekeni kokumelana, amanani angahlukaniswa ngemigqa eminingana e6, E12, kanye ne-E24. Uma ukubekezelela kokumelana kuncane, ngenani elingaphezu kwamahlelo.
I-voltage ephezulu yabaphikisi be-chip ingu-200v. Lokhu kufinyelela okuphezulu nakho kuthola amandla ajwayelekile ngokufakwa okulula. Kungakho lapho kudluliswa amandla amakhulu, ngokwesibonelo 500V, kufanelekile ukubeka abaphikisi abaningana abaxhumekile ochungechungeni.
