MCP3424-E/SL IC ADC 18BIT SIGMA-DELTA 14SOIC

Kev piav qhia

MCP3422, MCP3423 thiab MCP3424 li (MCP3422/3/4) yog cov suab nrov qis thiab qhov tseeb 18-Bit delta-sigma analog-to-digital (ΔΣ A/D) converter tsev neeg ntawm MCP342X series los ntawm Microchip Technology Inc. Cov khoom siv no tuaj yeem hloov pauv cov khoom siv analog rau cov lej digital nrog txog 18 qhov kev daws teeb meem.Lub on-board 2.048V siv voltage enables ib tug input range ntawm ± 2.048V txawv (tag nrho scale range = 4.096V / PGA).Cov khoom siv no tuaj yeem tso tawm cov txiaj ntsig analog-rau-digital hloov dua siab tshiab ntawm tus nqi ntawm 3.75, 15, 60, lossis 240 tus qauv ib ob nyob ntawm tus neeg siv tswj tau qhov teeb tsa me ntsis siv ob-xaim I2C serial interface.Thaum txhua qhov hloov dua siab tshiab, lub cuab yeej ntsuas qhov offset thiab nce qhov yuam kev tau.Qhov no muab qhov tseeb hloov dua siab tshiab los ntawm kev hloov pauv mus rau kev hloov pauv ntawm qhov hloov pauv ntawm qhov kub thiab lub zog hloov pauv.Tus neeg siv tuaj yeem xaiv PGA nce ntawm x1, x2, x4, lossis x8 ua ntej qhov hloov pauv hloov pauv-rau-digital tshwm sim.Qhov no tso cai rau MCP3422/3/4 pab kiag li lawm los hloov lub teeb liab input tsis muaj zog heev nrog kev daws teeb meem siab.Cov khoom siv MCP3422/3/4 muaj ob hom kev hloov dua siab tshiab: (a) Ib-Shot Conversion hom thiab (b) Continuous Conversion mode.Hauv Ib-Shot hloov dua siab tshiab hom, lub cuab yeej ua ib qho kev hloov dua siab tshiab thiab nkag mus rau qhov tsis tshua muaj tam sim no standby hom kom txog thaum nws tau txais lwm cov lus txib hloov dua siab tshiab.Qhov no txo ​​cov kev siv tam sim no zoo heev thaum lub sijhawm tsis ua haujlwm.Nyob rau hauv Nruam conversion hom, lub conversion yuav siv sij hawm qhov chaw tsis tu ncua ntawm lub teeb conversion ceev.Lub cuab yeej hloov kho nws cov zis tsis nrog cov ntaub ntawv hloov dua siab tshiab tsis ntev los no.
