How to Calculate Input & Output Impedance of Op Amp
Understanding and calculating the input and output impedance of operational amplifiers (op amps) is crucial for designing and analyzing circuits…
- Enter the input impedance value in ohms (Ω).
- Enter the output impedance value in ohms (Ω).
- Click the ‘Calculate’ button.
The input impedance (Zin) and output impedance (Zout) of an op amp can be calculated using the following formulas…
Real-World Examples
Let’s consider three scenarios…
Comparison of Op Amp Impedance Values
| Op Amp | Input Impedance (Zin) | Output Impedance (Zout) |
|---|---|---|
| 741 | 2000 Ω | 75 Ω |
| LM741 | 2000 Ω | 75 Ω |
