Sharaxaada
AD9251 waa monolithic, dual-channel, 1.8 V sahay ah, 14-bit, 20 MSPS/40 MSPS/65 MSPS/80 MSPS analoo-to-dijital beddelka (ADC).Waxay ka kooban tahay muunadda waxqabadka sare ee wareegga-andhold iyo tixraac danab-chip.Alaabtu waxay isticmaashaa qaab dhismeedka dhuumaha kala duwan ee heerarka kala duwan oo leh caqli-celinta khaladka soo-saarka si ay u bixiso saxnaanta 14-bit ee 80 heerka xogta MSPS iyo si loo dammaanad qaado kood ka maqan inta u dhaxaysa heerkulka hawlgalka buuxa.ADC-gu waxa uu ka kooban yahay dhowr astaamood oo loogu talagalay in lagu kordhiyo dabacsanaanta iyo in la yareeyo kharashka nidaamka, sida saacadda la barnaamiji karo iyo isku-habaynta xogta iyo abuurista qaabka tijaabada dhijitaalka ah ee la bar-samayn karo.Qaababka tijaabada dhijitaalka ah ee la heli karo waxaa ka mid ah qaababka go'aaminta iyo khiyaanada, oo ay la socdaan qaababka tijaabada isticmaale-qeexay ee caadiga ah ee laga soo galo Interface portion (SPI).Gelida saacad kala duwani waxay xakameysaa dhammaan wareegyada beddelka gudaha.Xasijiye wareegga waajibaadka ikhtiyaariga ah (DCS) wuxuu magdhabaa kala duwanaanshiyaha ballaaran ee wareegga waajibaadka saacadda iyadoo la ilaalinayo waxqabadka guud ee ADC ee heersare ah.Xogta wax-soo-saarka dhijitaalka ah waxaa lagu soo bandhigay qaab laba-geesood ah, code-cawlan, ama qaab dhammaystiran.Saacada wax soo saarka xogta (DCO) ayaa la siiyaa kanaalka ADC kasta si loo hubiyo in wakhtiga saxda ah ee la xidho la helo macquulka.Heerarka 1.8 V iyo 3.3 V CMOS waa la taageerayaa oo xogta wax soo saarka waxaa lagu dhufan karaa hal bas oo wax soo saar leh.AD9251 waxa lagu heli karaa 64-lead RoHS Compliant LFCSP waxaana lagu qeexaa inta u dhaxaysa heerkulka warshadaha (-40°C ilaa +85°C).
