Non-Inverting Op-Amp Resistor Calculator

The Formula

The formula for calculating the gain of a non-inverting op-amp is:

\[Gain = 1 + \frac{R2}{R1}\]

Rearranging this to solve for R2:

\[R2 = R1 * (Gain - 1)\]

Where:

• Gain: The desired amplification factor
• R1: The feedback resistor connected to the inverting input
• R2: The resistor connected between the inverting input and ground

How to Use

1. Enter the desired gain for your non-inverting op-amp circuit
2. Enter the value for R1 in ohms
3. Click "Calculate" to determine the required value for R2
4. The calculator will display the result and show the step-by-step calculation

Applications

Non-inverting op-amp configurations are widely used in various electronic applications, including:

• Audio amplifiers
• Sensor signal conditioning
• Voltage buffers
• Precision voltage amplifiers

This calculator helps you quickly determine the resistor values needed to achieve a specific gain in your non-inverting op-amp circuit design.
