Zida za MCP3422, MCP3423 ndi MCP3424 (MCP3422/3/4) ndizophokoso lochepa komanso zolondola kwambiri za 18-Bit delta-sigma analog-to-digital (ΔΣ A/D) zosinthira m'banja la mndandanda wa MCP342X kuchokera ku Microchip Technology Inc. Zidazi zimatha kusintha zolowetsa zaanalogi kukhala ma code adijito okhala ndi ma bits 18 otsimikiza.Mphamvu yamagetsi ya 2.048V pa board imathandizira kuyika kwa ± 2.048V mosiyanasiyana (sikelo yonse = 4.096V/PGA).Zipangizozi zimatha kutulutsa zotsatira za kutembenuka kwa analogi kupita ku digito pamitengo ya 3.75, 15, 60, kapena 240 zitsanzo pa sekondi iliyonse kutengera zosintha zosinthika za wosuta pogwiritsa ntchito mawonekedwe amtundu wa I2C wamawaya awiri.Pa kutembenuka kulikonse, chipangizo calibrates kuchepetsa ndi kupeza zolakwika basi.Izi zimapereka zotsatira zolondola za kutembenuka kuchokera ku kutembenuka kupita ku kusintha kwa kutentha ndi kusinthasintha kwa magetsi.Wogwiritsa ntchito amatha kusankha phindu la PGA la x1, x2, x4, kapena x8 kutembenuka kwa analogi kupita ku digito kusanachitike.Izi zimalola zida za MCP3422/3/4 kuti zisinthe chizindikiro choloŵa chofooka kwambiri ndi kusamvana kwakukulu.Zipangizo za MCP3422/3/4 zili ndi njira ziwiri zosinthira: (a) Kuwombera Kumodzi Kutembenuka ndi (b) Kutembenuka Kopitiriza.Mu mawonekedwe a One-Shot conversion, chipangizochi chimapanga kutembenuka kamodzi ndikulowa mumayendedwe otsika apano mpaka atalandira lamulo lina lotembenuka.Izi zimachepetsa kugwiritsiridwa ntchito kwamakono kwambiri panthawi yopanda ntchito.Mu mosalekeza kutembenuka akafuna, kutembenuka kumachitika mosalekeza pa anapereka kutembenuka liwiro.Chipangizochi chimasinthiratu buffer yake ndi data yaposachedwa kwambiri yosinthira.
