Koj paub dab tsi txog cov khoom siv hluav taws xob digital?
Hauv cov ntawv thov uas yooj yim siv thiab tsis tas yuav muaj ntau qhov kev hloov pauv, cov khoom siv hluav taws xob analog muaj qhov zoo dua vim tias lawv cov phiaj xwm thov tuaj yeem ua tiav los ntawm kev kho vajtse ruaj khov. Hauv cov ntawv thov kev ua haujlwm siab uas muaj ntau yam tswj tau, nrawm dua lub sijhawm teb ceev, xav tau ntau yam kev tswj hwm lub zog analog, thiab nyuaj, cov khoom siv hluav taws xob digital muaj qhov zoo dua. Tsis tas li ntawd, nyob rau hauv ntau txoj kev lag luam, piv rau analog fais fab khoom siv, cov khoom siv hluav taws xob digital yog siv los ntawm software programming rau ntau yam kev siv. Lawv scalability thiab reusability ua rau cov neeg siv tau yooj yim hloov cov kev ua hauj lwm tsis thiab optimize lub hwj chim systems. Los ntawm kev tiv thaiv overcurrent thiab tswj lub sijhawm tiag tiag, nws tuaj yeem txo tus naj npawb ntawm cov khoom siv peripheral.

Los ntawm kev tiv thaiv overcurrent thiab tswj lub sijhawm tiag tiag, nws tuaj yeem txo tus naj npawb ntawm cov khoom siv peripheral.
Cov khoom siv hluav taws xob digital tuaj yeem tswj tau los ntawm DSP lossis MCU. Kev hais lus zoo, DSP tswj cov khoom siv hluav taws xob siv cov kev lim dej digital, uas tuaj yeem ua tau raws li cov kev xav tau ntawm lub zog, muaj lub sijhawm teb ceev ceev, thiab kev tswj hwm lub zog zoo dua li MCU tswj cov khoom siv hluav taws xob.
Dab tsi yog cov txiaj ntsig ntawm cov khoom siv hluav taws xob digital
Ua ntej, nws yog programmable, thiab tag nrho cov haujlwm xws li kev sib txuas lus, nrhiav pom, telemetry, thiab lwm yam tuaj yeem siv los ntawm software programming. Tsis tas li ntawd, cov khoom siv hluav taws xob digital muaj kev ua haujlwm siab thiab kev ntseeg tau, thiab hloov tau yooj yim.
Kev cuam tshuam: Hauv microcontrollers, muaj kev cuam tshuam zoo ntawm cov digital thiab analog qhov chaw, vim tias cov teeb liab digital yog lub teeb liab mem tes nrog qhov dav dav; Tsis tsuas yog cov khoom siv hluav taws xob digital thiab cov khoom siv hluav taws xob analog feem ntau sib cais thiab txuas nrog cov ntxaij lim dej, tab sis qee qhov xav tau, xws li thaum lub AD converter hauv qee lub microcontrollers ua AD hloov dua siab tshiab, cov digital feem ntau yuav tsum tau nkag mus rau hauv lub xeev pw tsaug zog, thiab loj heev. Feem ntau ntawm cov logic digital tsis ua haujlwm los tiv thaiv lawv los ntawm kev cuam tshuam nrog qhov analog. Yog tias qhov cuam tshuam loj heev, txawm tias ob lub zog sib cais tuaj yeem siv tau, feem ntau yog cais los ntawm inductance thiab capacitance. Koj tseem tuaj yeem txuas cov khoom siv hluav taws xob digital thiab analog ntawm tag nrho pawg thawj coj sib cais, thiab txuas ncaj qha mus rau cov pob qij txha ntawm lub hwj chim lim capacitor los ntawm kev sib cais. Yog hais tias cov kev cai rau kev tiv thaiv kev cuam tshuam tsis siab, lawv kuj tuaj yeem txuas tau yooj yim ua ke.
