1. What is a Current to Voltage Converter?

Definition: This calculator computes the output voltage based on input current and gain factor of the converter.

Purpose: It helps electronics engineers and hobbyists design and analyze transimpedance amplifiers and current-to-voltage conversion circuits.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Output voltage (volts)
• \( I \) — Input current (amps)
• \( \text{gain} \) — Conversion gain (volts/amp)

Explanation: The input current is multiplied by the gain factor to determine the output voltage.

3. Importance of Current-to-Voltage Conversion

Details: Current-to-voltage conversion is fundamental in many electronic applications including sensor interfaces, photodiode amplifiers, and signal processing circuits.

4. Using the Calculator

Tips: Enter the current in amps and the gain in volts/amp (default 1 V/A). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical gain value?
A: Gain depends on the application. Common values range from 1 V/A for basic converters to 1,000 V/A or more for sensitive measurements.

Q2: Can this calculator be used for AC current?
A: Yes, but it calculates peak voltage for given peak current. For RMS values, additional calculations are needed.

Q3: What components affect the gain?
A: In a transimpedance amplifier, the feedback resistor primarily determines the gain (V/A).

Q4: How precise are these calculations?
A: The calculation is mathematically precise, but real-world circuits may have additional factors like bandwidth limitations and noise.

Q5: What's the maximum current I can input?
A: The calculator has no theoretical limit, but practical circuits are limited by component specifications.
