Frequently Asked Questions (FAQ)

What is an operational amplifier?

An operational amplifier (op-amp) is a type of integrated circuit that amplifies the voltage difference between its input terminals.

How do I calculate the gain of an op-amp?

The gain can be calculated using the formula: Gain (A_v) = 1 + (R_f / R_in).

What are some typical applications of op-amps?

Op-amps are used in signal conditioning, filtering, or to perform mathematical operations such as addition, subtraction, integration, and differentiation.

Can op-amps be used in both inverting and non-inverting configurations?

Yes, op-amps can be used in both inverting and non-inverting configurations to achieve different types of amplification.
