1. What is Op Amp Voltage Conversion?

The operational amplifier (op amp) voltage conversion calculates the output voltage based on the input voltage and the ratio of two resistors in a non-inverting amplifier configuration. This is fundamental in analog circuit design.

2. How Does the Calculator Work?

The calculator uses the op amp voltage conversion formula:

\[ V_{out} = V_{in} \times \left( \frac{R2}{R1} \right) \]

Where:

\( V_{in} \) — Input voltage (volts)
\( R2 \) — Feedback resistor (ohms)
\( R1 \) — Input resistor (ohms)
\( V_{out} \) — Output voltage (volts)

Explanation: The equation shows that the output voltage is proportional to the input voltage multiplied by the ratio of the two resistors.

3. Importance of Voltage Conversion

Details: Accurate voltage conversion is crucial for signal conditioning, amplification, and various analog circuit applications in electronics design.

4. Using the Calculator

Tips: Enter input voltage in volts, resistor values in ohms. All values must be positive, and resistors must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the ideal op amp assumption?
A: The calculation assumes infinite input impedance, zero output impedance, and infinite open-loop gain.

Q2: What are typical resistor values?
A: Common values range from 1kΩ to 100kΩ, but depend on specific application requirements.

Q3: Does this work for AC signals?
A: Yes, for frequencies within the op amp's bandwidth, the same formula applies to instantaneous voltages.

Q4: What about power supply limits?
Important: The output cannot exceed the op amp's supply voltages.

Q5: Can I use this for inverting configuration?
A: No, this calculator is for non-inverting configuration only. Inverting configuration has a different formula.
