Eroare OP AMP in Proteus 8


Recommended Posts

Op Amp-ul selectat de tine NU are model pentru simulare. Selecteaza alt OP amp care sa aiba model. Cand selectezi o componenta in Proteus in dreapta sus la preview se specifica daca are sau nu model de simulare.Alege unul cu "Schematic model ..." sau " SPICE model" .

La un pin oarecare (PIN 2 creat de mine) ii atasezi un TERMINALS de tip POWER, se va conecta automat, la fel si cu minus la o intrare gen PIN 2 sau alt pin ii atasezi GROUND.

Daca vrei sa-l alimentezi pentru simulare in loc de acel PIN 2 ii pui un GENERATORS de tip DC caruia ii dai o valoare egala cu tensiunea de alimentare.

Mai am o intrebare ...sper sa nu deranjez.. Cum fac alimentarea integratului in Proteus in schema de mai jos? imi da eroare ca nu am conectat pinii de alimentare ai IC.

 

In proteus circuitele logice se alimenteaza "automat" spre VCC/VDD. Teoretic in scema pusa de tine nu ar trebui sa ai probleme de alimentare. Nu acelasi lucru este valabil si cu OP amp-urile.

Chiar nu ma prind cum ai reusit sa alimentezi un op amp fara eroare si nu reusesti la un 74HCxx care se alimenteaza automat
