Where are operational amplifiers used?
In the most basic circuit, op-amps are used as voltage amplifiers, which can be broadly divided into noninverting and inverting amplifiers. Voltage followers (also simply called buffers) are a type of commonly used noninverting amplifiers. Op-amps are also used as differential amplifiers, integrator circuits, etc.
Why IC 741 is not used for high frequency applications?
Why IC 741 is not used for high frequency applications? IC741 has a low slew rate because of the predominance of capacitance present in the circuit at higher frequencies. As frequency increases the output gets distorted due to limited slew rate.
Can you give one practical example of an operational amplifier?
When an operational amplifier is combined with an amplification circuit, it can amplify weak signals to strong signals.It behaves like a megaphone where the input signal is a person’s voice and the megaphone is the operational amplifier circuit. For example, such a circuit can be used to amplify minute sensor signals.
Are op-amps still used?
Op-amps are still a primary building block for analog systems, performing tasks like amplification, active filtering, and signal transformation. In digital systems, op-amps are used in buffers, analog-to-digital converters, digital-to-analog converters, and regulated power supplies, to name a few applications.

Why it is called op-amp?
An operational amplifier (op-amp) is an integrated circuit (IC) that amplifies the difference in voltage between two inputs. It is so named because it can be configured to perform arithmetic operations.
Why it is called op amp?
Why do we need op-amps?
These devices perform useful tasks, including addition, multiplication, differentiation, integration, and feedback control. Op-amps are still a primary building block for analog systems, performing tasks like amplification, active filtering, and signal transformation.
What are the advantages of op-amp?
Advantages: increased circuit stability, ▪ increased input impedance, ▪ decreased output impedance, increased frequency bandwidth at constant gain.
What is the drawback of op-amp IC 741?
Answer: The drawback of IC 741 is its low slew rate (0.5v/µs), which limits its use in relatively high frequency applications, especially in oscillators, comparators and filters.
What is the supply voltage of IC 741?
Supply-voltage operating range for the 741 is +4.5 volts (minimum) to +18 volts (maximum), and it is specified for operation between +5 and +15 Vdc.
Where do you find applications of amplifiers?
They are used in the fields of process control, communications, computers, power and signal sources, displays and measuring systems. They are used in linear applications like voltage follower, differential amplifier, inverting amplifier, non-inverting amplifier, etc.
Why are op-amps so expensive?
Manufacturing costs between mass production and handmade exemplars differ dramatically. Good amps are so expensive because of common beliefs in what is good. As the result, mass produced amps contrary to common beliefs are bad, while really good amps are made in low quantities.

What is the symbol of op-amp?
The symbol for an operational amplifier is a triangle that has two inputs and a single output. This symbol is shown below in figure 2. The input with a positive sign is called the non-inverting terminal and the input with the negative sign is called the inverting terminal.
Do op-amps work with DC?
The basic Op-amp construction is of a 3-terminal device, with 2-inputs and 1-output, (excluding power connections). An Operational Amplifier operates from either a dual positive ( +V ) and an corresponding negative ( -V ) supply, or they can operate from a single DC supply voltage.
Why is it called op-amp?
Why is it called operational amplifier?
Op-Amp (operational amplifier)
Originally, op-amps were so named because they were used to model the basic mathematical operations of addition, subtraction, integration, differentiation, etc. in electronic analog computers. In this sense a true operational amplifier is an ideal circuit element.
