Operationsverstärker

Beitragvon #48 » 18.07.2011, 07:10

Tach leute :)
Ich brauche um mir eine OP schaltung zubauen eine Spannungsversorgung von +15 und -15 V.
+15V hab ich, jetzt wollte ich mir mit einer diodenbrücke +15 und -15 V machen.
haut aber noch nicht ganz hin.
ich habe ein labornetzteil was bis +32V geht.
kann mir bitte jemand helfen oder einen Schaltplan schicken.
;) danke im vorraus.

Zeig mal den Schaltplan deiner Diodenbrücke. Es ist nicht ganz so einfach aus +32V +/-15 Volt zu machen. Dafür braucht man mehr als nur Dioden.

Hallo im Forum! :D

Wie kommst du auf die Idee sowas mit einer "Diodenbrücke" zu versuchen?

Schau auf die Elektronikerseite -> Grundlagen -> Lehrgänge -> Symmetrische Spannungsversorgung.
Da siehst du wie es für 9 V gemacht wird. Bei 32 V ist es auch nicht wesentlich anders :wink:

Ich hab ein labornetzteil das geht von 0,1 bis 32 volt das kann ich einstellen.
ok danke die schaltung hilft weiter ;)
habs hinbekommen.
