So berechnen Sie Op Amp Gain
learn.whatIsHeading
Calculates op-amp circuit gain for inverting and non-inverting configurations. Determines amplifier output voltage relationship to input.
Formel
Bandwidth = gain-bandwidth product ÷ gain
Schritt-für-Schritt-Anleitung
- 1Inverting: gain = -Rf ÷ Rin
- 2Non-inverting: gain = 1 + (Rf ÷ Rin)
- 3Bandwidth = gain-bandwidth product ÷ gain
- 4Input impedance affects signal source loading
Gelöste Beispiele
Eingabe
Rf=10k, Ri=1k
Ergebnis
Gain = -10
Häufige Fehler vermeiden
- ✕Forgetting negative sign for inverting configuration
- ✕Not checking gain-bandwidth product vs. requirements
Häufig gestellte Fragen
Why use non-inverting over inverting?
Non-inverting has higher input impedance, better for source impedance matching.
What limits op-amp gain?
Gain-bandwidth product: high gain reduces bandwidth; stability requires compensation.
