Nesto oko hladjenja...
#55
Mene interesuje da li moze da se ta greska popravi ako trimujemo taj offset posto vecina jednostrukih OP-ova ima nozice za to.
Tu se jos mesa temperaturni drift tog ofseta jer ako ga nuliramo pri jednoj temperaturi on ce da "odkliza" pri drugoj temperaturi ... To je neminovna pojava kada radimo sa sentovima vrlo male otpornosti (jer smo hteli da smanjimo discipaciju na njemu) a na svu tu muku sam shent ima svoj temperaturni koeficijent pa to sve bude jos problematicnije ...
Parce PCB voda koji spaja tacke izmedju shenta i tranzistora i ostali power vodovi isto imaju tempco sto dodatno unosi greske ...
Obavezno koga interesuje ta problematika da pogleda seriju video predavanja koju sam gore linkivao, recimo bez problema objasne realan problem sa greskom vecom od 40-70%, kad dodju na 10% za ceo opseg bude "ne pipaj nista vise, dobro smo prosli" Smile
