Calculates op-amp circuit gain for inverting and non-inverting configurations. Determines amplifier output voltage relationship to input.

सूत्र

Bandwidth = gain-bandwidth product ÷ gain

चरण-दर-चरण मार्गदर्शिका

  1. 1Inverting: gain = -Rf ÷ Rin
  2. 2Non-inverting: gain = 1 + (Rf ÷ Rin)
  3. 3Bandwidth = gain-bandwidth product ÷ gain
  4. 4Input impedance affects signal source loading

हल किए गए उदाहरण

इनपुट
Rf=10k, Ri=1k
परिणाम
Gain = -10

सामान्य गलतियां जिनसे बचना है

  • Forgetting negative sign for inverting configuration
  • Not checking gain-bandwidth product vs. requirements

अक्सर पूछे जाने वाले प्रश्न

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.
