Izingxenye Ze-elekthronikhi Ezintsha Nezangempela ze-Semicon LM50CIM3X/NOPBIC CHIPS Amasekethe Ahlanganisiwe Esitoko
Amadivayisi e-LM50 kanye ne-LM50-Q1 ayizinzwa zokushisa ezididiyelwe ezinembayo ezikwazi ukuzwa ububanzi bezinga lokushisa -40°C ukuya ku-125°C zisebenzisa isiphiwo esisodwa esihle.I-voltage ephumayo yedivayisi ilingana ngokulinganayo nezinga lokushisa (10 mV/°C) futhi ine-DC offset engu-500 mV.I-offset ivumela ukufunda amazinga okushisa angalungile ngaphandle kwesidingo sokuhlinzekwa okungalungile.
I-voltage ekahle yokukhiphayo ye-LM50 noma i-LM50-Q1 isuka ku-100 mV iye ku-1.75 V ebangeni lokushisa -40°C kuya ku-125°C.I-LM50 ne-LM50-Q1 akudingi ukulinganisa kwangaphandle noma ukusikwa ukuze kunikeze ukunemba okungu-±3°C ekamelweni lokushisa kanye no-±4°C ngaphezu kwebanga lokushisa eligcwele -40°C kuya ku-125°C.Ukunquma nokulinganisa kwe-LM50 ne-LM50-Q1 ezingeni le-wafer kuqinisekisa izindleko eziphansi nokunemba okuphezulu.
Ukukhishwa komugqa, i-500 mV offset, nokulinganiswa kwefekthri kwe-LM50 ne-LM50-Q1 kwenza izimfuneko zesekhethi zibe lula endaweni eyodwa yokuhlinzeka lapho kufundwa amazinga okushisa angemahle.
Ngenxa yokuthi i-current ethule ye-LM50 ne-LM50-Q1 ingaphansi kuka-130 µA, ukuzifudumeza ngokwakho kukhawulelwe ku-0.2°C ophansi kakhulu emoyeni onganyakazi. -
