Sa inteleg ca nu corespund pinii. Compar foile de catalog ale OPA-urilor. Multumesc, Dr. Led.LE. am comparat foile de catalog si am constatat ca OPA 277 are un singur operational, deci trebuiesc 2 bucati iar OPA 2277 este identic la pini cu LM 358.

Exact.OPA277 are si reglaj de offset, ceea ce duce la realizarea unui instrument cat se poate de precis.Ca pret, OPA2277 = 2x OPA277
