Op Amp Gain Calculator (Inverting & Non-Inverting)

This calculator helps determine the voltage gain of operational amplifier (op-amp) circuits, specifically for inverting and non-inverting configurations. It simplifies the process of calculating gain by requiring only resistor values as inputs.

Usage Instructions:

• Select the op-amp configuration (inverting or non-inverting).
• Enter the resistor values (R1 and R2) in ohms.
• The calculator will automatically compute the voltage gain.

Key Features:

• Supports both inverting and non-inverting configurations.
• Instant calculation with real-time results.
• Clear labels for input fields and results.

Formulas Used:

Example Calculations:

• Inverting: If R1 = 1kΩ and R2 = 10kΩ, Gain = -10.
• Non-Inverting: If R1 = 1kΩ and R2 = 10kΩ, Gain = 11.

Practical Applications:

This calculator is useful for designing audio amplifiers, signal conditioning circuits, and other analog electronics projects where precise gain control is required.

Notes:

• Ensure resistor values are positive and non-zero.
• The calculator assumes an ideal op-amp (infinite gain, infinite input impedance, zero output impedance).
