Operational Amplifier (Op-Amp)
Introduction:
An operational amplifier, often referred to as an op-amp, is a versatile and widely used electronic component in various applications. It is a linear integrated circuit that operates as a voltage amplifier with very high gain.
Characteristics of an Operational Amplifier:
1. High Voltage Gain: The op-amp has a very high voltage gain, typically in the range of 10^5 to 10^6. This high gain allows the op-amp to amplify small input signals to a larger output signal.
2. Direct Coupled Amplifier: An operational amplifier is a direct coupled amplifier, which means it is capable of amplifying both AC and DC signals. It amplifies the input signal without the need for any coupling capacitors or transformers.
3. Usefulness: An op-amp is not limited to amplifying AC signals only. It can be used for various applications such as amplification, filtering, signal conditioning, waveform generation, mathematical operations, etc.
4. Mathematical Operations: One of the key features of an operational amplifier is its ability to perform mathematical operations. It can be used to add, subtract, multiply, differentiate, integrate, and perform other mathematical operations on input signals.
Explanation:
The statement that is incorrect for an operational amplifier is option 'C', which states that it is only useful for amplifying AC signals. This statement is incorrect because an op-amp can amplify both AC and DC signals. It is not limited to amplifying only AC signals.
Conclusion:
In summary, an operational amplifier is a versatile electronic component with high voltage gain, capable of amplifying both AC and DC signals. It is a direct coupled amplifier and can be used for various applications, including mathematical operations.
