Op-Amp Calculator
Calculate operational amplifier circuit parameters for multiple configurations including gain, impedance, bandwidth, and power analysis with detailed explanations and formulas.
Inverting Amplifier Configuration
The inverting amplifier configuration produces an output that is 180° out of phase with the input signal. The gain is determined by the ratio of feedback resistor to input resistor.

Op-Amp Configuration Guide
Inverting Amplifier
- • 180° phase shift
- • Moderate input impedance
- • Gain determined by R2/R1
- • Stable and predictable
Non-Inverting
- • No phase shift
- • Very high input impedance
- • Gain ≥ 1
- • Excellent for buffering
Differential
- • Amplifies difference
- • Rejects common-mode
- • Excellent noise rejection
- • Ideal for sensors
Integrator
- • Performs integration
- • Low-pass characteristic
- • Phase lag of 90°
- • Used in analog computers
Differentiator
- • Performs differentiation
- • High-pass characteristic
- • Phase lead of 90°
- • Sensitive to noise
Buffer/Follower
- • Unity gain (Av = 1)
- • Maximum input impedance
- • Minimum output impedance
- • Perfect for isolation
