Sharaxaada
Qalabka MCP3422, MCP3423 iyo MCP3424 (MCP3422/3/4) waa qaylada hoose iyo saxnaanta sare 18-Bit delta-sigma analog-to-digital (ΔΣ A/D) xubnaha qoyska ee taxanaha MCP342X ee Microchip Technology Inc. Qalabkani waxa ay u rogi karaan agabka analooga ah una rogi kara koodh dhijitaal ah oo leh ilaa 18 bit oo xallin ah.Korantada tixraaca ee dusha sare ee 2.048V waxay awood u siineysaa kala duwanaansho wax gelinta ± 2.048V si ka duwan (kala duwanaanta cabbirka buuxa = 4.096V/PGA).Aaladahani waxay soo saari karaan natiijooyinka is-beddelka analog-to-dijitaalka ah ee heerarka 3.75, 15, 60, ama 240 muunado ilbiriqsi kasta iyadoo ku xidhan isticmaaleha la xakameyn karo ee dejimaha qaniinyada qaabeynta iyadoo la adeegsanayo is-dhexgalka labada-siliga I2C.Inta lagu guda jiro beddelaad kasta, qalabku wuxuu si toos ah u hagaajinayaa oo u helayaa khaladaadka si toos ah.Tani waxay ku siinaysaa natiijooyin sax ah oo beddelaad ka beddelka beddelka isbeddelka heerkulka iyo isbeddelka saadka.Isticmaaluhu waxa uu dooran karaa faa'iidada PGA ee x1, x2, x4, ama x8 ka hor inta aan la samayn analoog-to-dijital beddelidda.Tani waxay u oggolaanaysaa aaladaha MCP3422/3/4 inay u beddelaan signal-gelin aad u daciif ah oo leh xallin sare.Aaladaha MCP3422/3/4 waxay leeyihiin laba qaab beddelasho: (a) Habka beddelka hal-shot iyo (b) Habka beddelka joogtada ah.Habka beddelka Hal-Shot, qalabku waxa uu sameeyaa beddelaad keliya oo waxa uu si toos ah u galaa hab-sugitaan hoose oo hadda jira ilaa uu ka helayo amar beddelaad kale.Tani waxay si weyn u yaraynaysaa isticmaalka hadda jira xilliyada shaqo la'aanta.Qaab beddelaad joogto ah, beddelaaddu waxay si joogto ah u dhacdaa xawaaraha beddelka ee go'an.Qalabku wuxuu ku cusboonaysiiyaa wax-soo-saarkiisa xog-is-beddelka ugu dambeeyay.
