Kev tsis
ADM483AR RS-485 transceiver, tus cwj pwm los ntawm kev ua raws li EIA RS-485/RS-422 cov qauv, sawv ua ntau yam kev daws teeb meem rau kev sib txuas lus sib txuas. Ua haujlwm ntawm cov ntaub ntawv tus nqi txog li 250 kbps, nws muaj kev siv hluav taws xob tsawg (120 μA) thiab txo qis qis rau kev txo EMI. Txhawb nqa mus txog 32 transceivers ntawm ib lub tsheb npav, nws muab kev yooj yim hauv kev tsim qauv. Cov yam ntxwv tseem ceeb suav nrog ntau hom kev sib txawv (-7 V rau +12 V), cov zis siab impedance thaum muaj kev tsis taus, thiab cov txheej txheem tiv thaiv zoo li thermal kaw thiab tiv thaiv luv luv. Pin compatibility nrog MAX483 thiab qhov ntsuas kub ntawm -40 degree rau +85 degree ntxiv txhim kho nws qhov kev thov, ua rau ADM483AR muaj kev xaiv muaj zog thiab muaj txiaj ntsig rau cov ntawv thov uas xav tau cov ntaub ntawv txhim khu kev qha kis mus ntev.

Yam khoom:
ADM483 yog ib qho hluav taws xob sib txawv ntawm cov kab hluav taws xob uas tsis tshua muaj hluav taws xob sib txawv tsim nyog rau kev sib txuas lus ib nrab-duplex cov ntaub ntawv ntawm ntau cov kab tsheb npav. Nws yog tsim los rau kev sib npaug ntawm cov ntaub ntawv sib kis, thiab ua raws li EIA Standards RS-485 thiab RS-422.Qhov no muaj cov kab sib txawv tsav tsheb thiab tus neeg txais kab sib txawv. Ob leeg sib koom tib tus pins sib txawv, nrog rau tus tsav tsheb lossis tus txais tau qhib rau txhua lub sijhawm.
Cov cuab yeej muaj qhov input impedance ntawm 12 kΩ, tso cai rau 32 transceivers ntawm ib lub npav. Txij li thaum tsuas yog ib tus neeg tsav tsheb yuav tsum tau qhib txhua lub sijhawm, qhov tso tawm ntawm tus neeg xiam oob khab lossis tus tsav tsheb tsis muaj zog yog peb teev kom tsis txhob overloading lub npav. Qhov siab impedance tsav tsheb tso zis no yog tswj hwm tag nrho cov hom-hom voltage ntau ntawm -7 V txog +12 V.
Lub receiver muaj qhov ua tsis tau zoo uas ua rau muaj qhov ua tau zoo ntawm lub xeev cov zis yog tias cov inputs tsis sib txuas (floating).
Cov neeg tsav tsheb tso tawm yog slew-rate txwv kom txo EMI thiab cov ntaub ntawv yuam kev tshwm sim los ntawm kev cuam tshuam los ntawm cov tsheb npav tsis raug cai. Lub zog ntau dhau los ntawm kev sib cav hauv tsheb npav lossis los ntawm kev tso tawm luv luv yog tiv thaiv los ntawm thermal shutdown circuit.
Ib feem yog tag nrho teev nyob rau hauv kev lag luam kub ntau, thiab muaj nyob rau hauv ib tug 8- lead SOIC pob.
