    op-amp (operational amplifier) Gain Calculator

    input signal is amplified by the operational amplifier (op-amp) is known as the op-amp gain. Usually, it is shown as the output voltage divided by the input voltage. This tool calculates the overall capacitance value for multiple capacitors connected either in series.

    Op-amp gain Calculator - op-amp (operational amplifier) gain equations:

    Inverting Operational Amplifier gain formula:

    Ainv = VoutVin = RfRin

    For Example, no-inverting gain calculation: Rf = 10,000Ω (10kΩ) feedback resistor, Rin = 2,000Ω (2KΩ) input resistor, Input voltage Vin = 1V


    Ainv = VoutVin = 100002000Ainv = -5V

    Non-Inverting Operational Amplifier gain formula:

    Anon-inv = VoutVin = 1 + RfRin

    For Example, no-inverting gain calculation: Rf = 10,000Ω (10kΩ) feedback resistor, Rin = 2,000Ω (2KΩ) input resistor, Input voltage Vin = 1V


    Anon-inv = VoutVin = 1 + 10002000Anon-inv = 6V

    Frequently Asked Questions - Name Conversion FAQs:

    What does "inverting" mean?

    This implies that the output signal is exactly the inverted of the input signal. If you enter a good number, up comes a bad number.

    What is the significance of resistors in the circuit?

    This allows the signal that flows through to be controlled by resistors and thus determines how strong the output signal will be.

    Is it possible to use only audio signals with an inverting op amp?

    No, a laser microphone can work almost with any type of electrical signal (voltages from sensors, for example, or even signals in computers)

    And what if I don’t use resistors?

    Without a resistor, the circuit may not give or do the correct things. This could all lead to too much current being carried, damaging the op-amp or other components.

    Is it so hard to create an inverting op amp circuit?

    Not at all! Even beginners should be able to make a working one with the right components and a simple breadboard after a bit of practice.

    What is the difference between an inverting and a non-inverting op amp?

    An inverting op-amp flips (inverts) the output signal so it is upside down whereas a non-inverting op-amp doubles the input to give you an equal signal except stronger.

    Can I then use any signal for a non-inverting op-amp?

    Yes! Many types of signals, such as audio, light, and temperature signals can be amplified using non-inverting op-amps.

    Is a power supply required for non-inverting op-amps?

    Of course, they need a positive and a negative power supply.

    What does voltage gain mean?

    It means that the output signal is as strong as its input, and can be said 'n' times. When a gain is 5, then the output is 5 times greater than the input.

    Where can I get non-integrating op amps?

    Electronic stores or online stock non-inverting op-amps. Very often they are used in DIY electronics projects.
