ISemicon emitsha kunye neNqanaba yoMxholo we-Eletroniki LM50CIM3X/NOPBIC CHIPS IiSekethe eziDityanisiweyo kuMfanekiso oFakelweyo

inkcazelo emfutshane:

Izixhobo ze-LM50 kunye ne-LM50-Q1 zichanekile zidibeneyo-iinzwa zobushushu zesetyhula ezinokuva -40 ° C ukuya kwi-125 ° C ububanzi beqondo lokushisa usebenzisa unikezelo olulodwa olufanelekileyo.Umbane wemveliso wesixhobo uhambelana ngokuhambelana nobushushu (10 mV / ° C) kwaye une-DC offset ye-500 mV.I-offset ivumela ukufunda amaqondo obushushu angalunganga ngaphandle kwesidingo sonikezelo olubi.
I-voltage efanelekileyo yokukhupha i-LM50 okanye i-LM50-Q1 isuka kwi-100 mV ukuya kwi-1.75 V kwi--40 ° C ukuya kwi-125 ° C.I-LM50 kunye ne-LM50-Q1 ayifuni nakuphi na ukulinganisa kwangaphandle okanye ukunqumla ukubonelela ngokuchaneka kwe-±3 ° C kwiqondo lokushisa kunye ne-± 4 ° C ngaphezu kwe-40 ° C epheleleyo ukuya kwi-125 ° C.Ukunciphisa kunye nokulinganisa kwe-LM50 kunye ne-LM50-Q1 kwinqanaba le-wafer liqinisekisa ixabiso eliphantsi kunye nokuchaneka okuphezulu.
Imveliso yomgca, i-500 mV offset, kunye nokulinganisa kwefektri ye-LM50 kunye ne-LM50-Q1 yenza lula iimfuno zokujikeleza kwindawo enye yokubonelela apho ukufunda amaqondo okushisa angalunganga kuyimfuneko.
Ngenxa yokuba i-quiescent current ye-LM50 kunye ne-LM50-Q1 ingaphantsi kwe-130 µA, ukuzifudumeza kulinganiselwe kwi-0.2 ° C ephantsi kakhulu emoyeni.

isivamvo?

1. Yintoni isivamvo?Iintlobo zezivamvo?Umahluko phakathi kwe-analog kunye ne-digital sensors?
Ii-Sensors zizixhobo eziqhelekileyo ezisetyenziselwa ukufumanisa utshintsho kwimeko yomzimba kunye nokulinganisa iziphumo zemilinganiselo kwizinga elithile okanye uluhlu.Ngokubanzi, abenzi boluvo banokwahlulwa babe ziintlobo ezimbini: i-analog kunye ne-digital sensors.Izinzwa zobushushu ezineziphumo ze-analog zisebenzisa imveliso ye-analog ukuhambisa ubushushu, kanti abenzi boluvo abaneziphumo zedijithali azifuni ukucwangciswa ngokutsha kwenkqubo kwaye banokuthumela ubushushu obumiselweyo ngokuthe ngqo.

Isivamvo se-analog?

2.Yintoni inzwa ye-analog?Yintoni esetyenziselwa ukubonisa ubungakanani beparamitha?
I-analog sensors ikhupha isignali eqhubekayo kwaye isebenzise i-voltage, yangoku, ukuchasana, njl njl ukubonisa ubukhulu beparameter elinganiswayo.Ngokomzekelo, i-sensor sensors, i-pressure sensors, njl. zi-analog sensors eziqhelekileyo.Ngokomzekelo, izixhobo ze-LM50 kunye ne-LM50-Q1 zichanekile zidibeneyo-iinzwa zeqondo lokushisa kweesekethe ezinokuva -40 ° C ukuya kwi-125 ° C ububanzi beqondo lokushisa usebenzisa unikezelo olulodwa oluhle.I-voltage efanelekileyo yokukhupha i-LM50 okanye i-LM50-Q1 isuka kwi-100 mV ukuya kwi-1.75 V kwi--40 ° C ukuya kwi-125 ° C.
Inzwa ye-analog eqhelekileyo ibona iparameter yangaphandle, njengoxinzelelo, isandi, okanye ubushushu, kwaye ibonelela ngombane we-analog okanye imveliso yangoku ngokuhambelana nexabiso layo elilinganisiweyo.Ixabiso lemveliso lithunyelwa kwi-sensor yokulinganisa kwikhadi le-analog efunda isampuli yokulinganisa kwaye iguqulelwe kwi-digital binary representation enokusetyenziswa yi-PLC / umlawuli.
Kwi-analog sensors, kunokuba yimfuneko ukulinganisa inzuzo ye-DC kunye ne-offset ukufezekisa ukuchaneka kwenkqubo efunekayo.Ukuchaneka kobushushu benkqubo akuqinisekwanga kwiphepha ledatha njengoko kuxhomekeke kakhulu kwimpazamo yesalathiso yeDC.Umbane wemveliso wesixhobo uhambelana ngokuhambelana nobushushu (10 mV / ° C) kwaye une-DC offset ye-500 mV.I-offset ivumela ukufunda amaqondo obushushu angalunganga ngaphandle kwesidingo sonikezelo olubi.

Inkcazelo yesivamvo sobushushu?
Isivamvo seqondo lobushushu sisiva esiva ubushushu kwaye sibuguqulele ekubeni sisiginali yemveliso esebenzisekayo.Izinzwa zobushushu ziyinxalenye engundoqo yezixhobo zokulinganisa ubushushu kwaye ziza kwiindidi ezininzi.Izivamvo zobushushu zichanekile kakhulu ekulinganiseni ubushushu be-ambient kwaye zisetyenziswa kakhulu kwezolimo, kushishino, kwiindibano zocweyo, iindawo zokugcina, kunye namanye amacandelo.

Ukuhlelwa

Ukuhlelwa kwesivamvo sobushushu
Imowudi yesibonisi sophawu lobushushu inokwahlulwa ngokubanzi ngokweendidi ezintathu: izinzwa zobushushu bedijithali, iisensom zeqondo lobushushu eliphuma kwi-logic, kunye ne-analog sensors.

Iingenelo

Izinto eziluncedo ze-analog sensor chips.
I-analog sensors yeqondo lokushisa, njenge-thermocouples, i-thermistors, kunye ne-RTD yokubeka iliso kwiqondo lokushisa, kwi-linearity ethile yomgangatho wokushisa, ayilungile, imfuno yembuyekezo ye-cold-end okanye imbuyekezo yokukhokela;inertia ye-thermal, ixesha lokuphendula licotha.Izinzwa ezidityanisiweyo zobushushu be-analog zineengenelo zobuntununtunu obuphezulu, umgca olungileyo, kunye nexesha lokuphendula elikhawulezayo xa kuthelekiswa nabo, kwaye ikwadibanisa isekethe yomqhubi, isekethe yokusetyenzwa komqondiso, kunye nesekethe yokulawula ingqiqo eyimfuneko kwi-IC enye, enenzuzo ubungakanani obusebenzayo obuncinci kunye nokusebenziseka ngokulula.

Isicelo

Iinkalo zesicelo se-analog sensors
Ukusetyenziswa kwezinzwa ze-analog kubanzi kakhulu, nokuba, kushishino, kwezolimo, kulwakhiwo lwezokhuselo lwesizwe, okanye kubomi bemihla ngemihla, imfundo kunye nophando lwesayensi, kunye nezinye iinkalo, umzobo we-analog sensors unokubonwa yonke indawo.
