1. There's a difference.
2.4558d and 5532 are common op amp chips, but they have some differences in the application of voltage follower.
4558d is a dual op amp chip, while 5532 is a single op amp chip. The
4558d has a higher gain and lower input bias current for applications that require higher gain and lower distortion.
While the 5532 has lower noise and higher bandwidth, it is suitable for applications requiring higher accuracy and a wider frequency range. In addition, 4558d and 5532 also have some differences in the supply voltage range, input resistance, output current and so on.
Therefore, when selecting the voltage follower chip, it is necessary to select the appropriate chip according to the specific application requirements.
The 4558D and 5532 are both common op amp chips, but they differ in a few ways. First, the 4558D is a dual op amp chip, while the 5532 is a single op amp chip. This means that the 4558D can process two signals at the same time, while the 5532 can only process one signal.
Secondly, the input voltage noise of 4558D is higher, while the input voltage noise of 5532 is lower. Therefore, when a higher signal-to-noise ratio is required, 5532 is more appropriate.
In addition, the 4558D has a narrow bandwidth, while the 5532 has a wider bandwidth, so the 5532 is more suitable for applications that require a higher frequency response. In general, the choice of 4558D or 5532 depends on the specific application requirements.
The conversion speed of NE5532 is faster than that of 4558, and the input pole of 5532 is MOS tube. 4558 is a regular triode. So overall 5532 is much better than 4558.
