Operational amplifier is a

Options

A. Digital IC
B. Linear IC
C. OR gate
D. AND gate

Answer

**Step-by-Step Solution:**

1. **Understanding the Options**:
- The question provides four options:
1. Digital IC
2. Linear IC
3. OR gate
4. AND gate

2. **Defining Operational Amplifier**:
- An operational amplifier (op-amp) is an electronic device that can amplify weak electrical signals. It is commonly used in various analog applications.

3. **Analyzing the Options**:
- **Digital IC**: These are integrated circuits that operate on digital signals (0s and 1s). An operational amplifier does not fall under this category.
- **Linear IC**: These are integrated circuits that can handle continuous signals and are capable of amplification. This is where the operational amplifier fits.
- **OR gate**: This is a digital logic gate that outputs true or high when at least one of its inputs is true. It is not an operational amplifier.
- **AND gate**: Similar to the OR gate, this is also a digital logic gate that outputs true only when all its inputs are true. Again, this is not an operational amplifier.

4. **Conclusion**:
- Based on the definitions and characteristics of the operational amplifier, the correct answer is **Linear IC**.

**Final Answer**: The operational amplifier is a **Linear IC**.
