Final Answer:
The LM308D op-amp is faster and wider than the 741 op-amp.
Step-by-step explanation:
The speed of an op-amp is determined by its bandwidth, which is the range of frequencies over which the op-amp can operate effectively. The LM308D has a higher gain-bandwidth product (GBP) than the 741, indicating that it can handle higher frequencies more effectively.
The GBP of the LM308D is approximately 6 MHz, while the GBP of the 741 is around 1.5 MHz. This means that the LM308D is faster in terms of its response to input signals and has a wider bandwidth, allowing it to handle a broader range of frequencies.
The calculation for bandwidth can be done using the formula: Bandwidth = GBP / Av, where GBP is the gain-bandwidth product and Av is the voltage gain. In this case, since the LM308D has a higher GBP, it will have a wider bandwidth compared to the 741. Therefore, the correct answer is option b) Faster, Wider.
In summary, the LM308D op-amp is faster and has a wider bandwidth compared to the 741 op-amp due to its higher gain-bandwidth product, allowing it to handle higher frequencies more effectively.
