Op-Amp Voltage and Gain Calculator

The Formulas

The formulas for calculating op-amp gain and output voltage depend on the configuration:

Inverting Configuration:

\[Gain = -\frac{R2}{R1}\] \[V_{out} = Gain \times V_{in}\]

Non-Inverting Configuration:

\[Gain = 1 + \frac{R2}{R1}\] \[V_{out} = Gain \times V_{in}\]

Where:

• Gain: The voltage amplification factor
• R1, R2: Resistor values in the feedback network
• V_in: Input voltage
• V_out: Output voltage

How to Use

1. Select the op-amp configuration (Inverting or Non-Inverting)
2. Enter the input voltage (V_in)
3. Enter the values for R1 and R2
4. Click "Calculate" to determine the gain and output voltage

Applications

Op-amp circuits are widely used in various electronic applications, including:

• Audio amplifiers
• Sensor signal conditioning
• Instrumentation amplifiers
• Active filters
• Voltage comparators

This calculator helps you quickly analyze both inverting and non-inverting op-amp configurations, making it easier to design and understand these versatile circuits.
