Question

Mention the characteristics of an ideal operational amplifier.

Answer 1

Answer:

characteristics of an ideal operational amplifier.:-

• Infinite Voltage Gain:- An ideal op amp will have infinite voltage gain. Op amps are devices that many times are used to function as amplifiers.
• Infinitely high input impedance
• Zero Output Impedance
• Gain Independent of Frequency In an ideal op amp, the gain that the op amp produces will be independent of frequency. This means that regardless of the frequency of the input signal going into the op amp, the gain that is produced will be constant and good across all frequencies.
• Zero Input Voltage Offset
• Positive and Negative Voltage Swings to Supply Rails
• Output swings instantly to the correct value

Answer 2

Answer:

An ideal op amp will display the following characeristics, of which are all explained in detail below. Ideal op amps will have infinite voltage gain, infinitely high impedance, zero output impedance, its gain is independent of input frequency, it has zero voltage offset, its output can swing positive or negative to the same voltages as the supply rails, and its output swings instantly to the correct value.
