What type of ICS are the operational amplifiers?
An op amp is a complex electronic device, which consists of resistors, capacitors, transistors and diodes. It is commercially available in integrated circuit form. Most commonly available and used op amp IC is IC 741. The IC 741 is a small chip.
What are the most common applications of op amps?
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 types of op amps?
Op amps can be classified into 3 main types based on the input/output voltage range: Dual Supply, Single Supply, and Rail-to-Rail.

What are the industrial applications of op amp?
Op-amps are used for a variety of applications such as AC and DC signal amplification, filters, oscillators, voltage regulators, comparators and in most of the consumer and industrial devices.
What is ideal op-amp?
Operational amplifier: The ideal op amp is an amplifier with infinite input impedance, infinite open-loop gain, zero output impedance, infinite bandwidth, and zero noise. It has positive and negative inputs which allow circuits that use feedback to achieve a wide range of functions.
Why op-amp has high gain?
The opamp inherently has an incredibly, unbelievably high voltage gain because it is a multistage, differentail amplifier designed to give that high voltage. The first two stages contribute to this gain by using current sources and active loads. Here, if the open loop gain is very high, we can ignore the “1”.
