Ai spus aproximativ corect.Ai In figura 12 pinii la toate amplificatoarele operationale recomnadate.Folosind tl072/ne5532:In figura 2 nu e desanata intrarea negativa/pozitiva dar se vede ca intrarea positiva IN+(pinul 3) este la masa si intrarea negativa IN-(pinul 2) este legata la semnal .Alimentarile sunt la pinii 4 si 8.

nu imi spuneti un echivalent pentru operationalul lm833, eu m-am uitat dupa tl072 ca e compatibil la pini si la tensiuni de alimentare dar nu stiu in rest

din cate stiu eu , sa ma contrazica cineva daca nu e asa, toate AO-urile fac acelasi lucru, deci trebuie sa ai grija sa le alimentezi corespunzator si sa le conectezi conform datasheet-ului. in rest calitatea e cea care le deosebeste.
