About Operational Amplifiers
Operational amplifiers (op-amps) are high-gain electronic voltage amplifiers with differential inputs. They are fundamental building blocks in analog electronics, used in amplification, filtering, and signal processing applications.
Op-Amp Design Tips
- Gain Formula: For inverting: Av = -Rf/R1, For non-inverting: Av = 1 + Rf/R1
- Input Impedance: Inverting: R1, Non-inverting: Very high (MΩ)
- Output Impedance: Very low (typically < 1Ω)
- Bandwidth: Gain-bandwidth product limits high-frequency response
- Slew Rate: Limits maximum rate of output voltage change
- Power Supply: Ensure adequate headroom for output swing
