## What are the practical application of op-amp?

Op amps are used in a wide variety of applications in electronics. Some of the more common applications are: as a voltage follower, selective inversion circuit, a current-to-voltage converter, active rectifier, integrator, a whole wide variety of filters, and a voltage comparator.

## What are the applications of op-amp as subtractor?

An op-amp based subtractor produces an output equal to the difference of the input voltages applied at its inverting and non-inverting terminals. It is also called as a difference amplifier, since the output is an amplified one.

**What is the purpose of using 3 op-amps?**

A three-op amp in-amp is a commonly-used structure that can amplify the differential signal while stripping off any common-mode voltage. An advantage of this circuit is that a single resistor that doesn’t need to be matched with any other resistor in the circuit determines the gain.

### Which of the following are application of op?

The applications of the op-amp are voltage comparator, Schmitt trigger, triangle wave oscillator, differentiator, and integrator.

### What are the applications of adder and subtractor using op-amp?

So the gain of amplifier is equal to one. The output voltage Vo is equal to the voltage applied to the non-inverting terminal minus the voltage applied to the inverting terminal; hence the circuit is called a subtractor….Op-Amp Adder and Subtractor Circuits.

V1 | V2 | V o/p |

2 | 2 | -4.06 |

5.8 | 2 | -8.04 |

**What are the applications of Subtractors?**

Subtractors are mostly used for performing arithmetical functions like subtraction, in electronic calculators as well as digital devices. Subtractors are used in processors to compute tables, addresses, etc. It is also useful for DSP and networking based systems.

## What is linear and non-linear applications?

A circuit is said to be linear, if there exists a linear relationship between its input and the output. Similarly, a circuit is said to be non-linear, if there exists a non-linear relationship between its input and output. Op-amps can be used in both linear and non-linear applications.
