Ne5532

[zahlm]

hi all, I'm looking at the TI datasheet of the NE5532 but, is there any difference between the 5532 and the 5532A?? I saw that the 5534A is less noisier than the 5534, but how about the 5532?

Thanks, zahlm

Its the same, lower noise for the 'A' version.

mmm, tell me I'm wrong but I have seen the datasheet of 3 manufacturers and the input noise of the 5532 and 5532A are the same: 5nV and 2.7pA. Have anyone noticed a difference in real applications?
Forgive me if the topic is stupid, but it looks strange to me

Zahlm,

I've used both and there is no audible difference. Different brands make more of a difference.
