Mixer cu CI LM3900

Recommended Posts

Salutare si LA MULTI ANI! tuturor membrilor.

  Vreau si eu sa-mi fac un mixer cu 4 intrari pentru un amplificator si am ceva nedumeriri,vreau sa folosesc C.I. LM3900: nu stiu cum sa fac pentru varianta stereo,se poate alimenta acest C.I. cu + GND si -GND sau doar +si- Vcc.sa folosesc doua pcb-uri separate cu potentiometrii stereo sau sa fac un  pcb in oglinda cu alimentare + GND - Vcc? Multumesc pentru lamuriri si sper ca am cautat bine dar nu am mai gasit discutii pe acest subiect.
