I-AD7760BSVZ-REEL IC ADC 24BIT SIGMA-DELTA 64TQFP

Inkcazo

I-AD7760 yintsebenzo ephezulu, i-24-bit Σ-Δ i-analog-to-digital converter (ADC).Idibanisa i-bandwidth yegalelo elibanzi kunye nesantya esiphezulu kunye neenzuzo ze-Σ-Δ ukuguqulwa ukufezekisa ukusebenza kwe-100 dB SNR kwi-2.5 MSPS, eyenza ilungele ukufunyanwa kwedatha yesantya esiphezulu.Uluhlu olubanzi oluguquguqukayo oludityaniswe neemfuno ezincitshisiweyo zokunqanda ukuchasana lula ukwenza inkqubo yoyilo.Isithinteli esidityanisiweyo sokuqhuba ireferensi, isandisi-lizwi esahlukileyo sokuphazamiseka komqondiso kunye nokutshintshwa komgangatho, iflegi engaphezulu, inzuzo yangaphakathi kunye neerejista zokulinganisa, kunye nesixhobo sokucoca i-FIR esisezantsi-pass esisezantsi senza i-AD7760 ibe sisixhobo sokufumana idatha esidityanisiweyo esifuna iperipheral encinci. ukhetho lwecandelo.Ukongeza, isixhobo sibonelela ngamazinga okunciphisa anokucwangciswa, kwaye isihluzo sedijithali seFIR sinokuhlengahlengiswa ukuba iimpawu ezingagqibekanga azifanelekanga kwisicelo.I-AD7760 ifanelekile kwizicelo ezifuna i-SNR ephezulu ngaphandle koyilo oluntsonkothileyo lwesiphelo sokwenziwa komqondiso.Igalelo lokwahluka lithathwa njengesampula ukuya kuthi ga kwi-40 MSPS yimodyuli ye-analog.Isiphumo semodyuli sisetyenzwa luluhlu lwezihluzo ezisezantsi, kunye nesihluzo sokugqibela esinemiqobo emiselweyo okanye enokucwangciswa ngumsebenzisi.Ireyithi yesampulu, i-frequencies yekona yokucoca, kunye nesantya segama lemveliso zisetwa yindibaniselwano ye-clock frequency yangaphandle kunye neerejista zoqwalaselo ze-AD7760.I-voltage yereferensi enikezelwe kwi-AD7760 imisela uluhlu lwegalelo le-analog.Ngereferensi ye-4 V, uluhlu lwegalelo le-analog yi-± 3.2 V ukuhluka okungafaniyo malunga nemodi eqhelekileyo ye-2 V. Le ndlela eqhelekileyo yokuxhatshazwa ingafezekiswa ngokusebenzisa i-amplifier ye-on-chip, ukunciphisa ngakumbi iimfuno zomoya wangaphandle.I-AD7760 ifumaneka kwi-paddle eveziweyo, i-64-lead TQFP kwaye icaciswe phezu koluhlu lwamaqondo obushushu boshishino ukusuka ku-−40°C ukuya +85°C.
