what is different between NE5532AP and NE5532P

All

Can anyone clearify what is different between NE5532AP and NE5532P?

Naret

  • The difference is that the 'A' version has the guaranteed maximum low frequency noise specification.

  • Yes NE5532Ap is supposed to be Low Noise. But we have been having riding noise issue generated from this component. We tested a number of our assemblies to locate the root cause and they all pointed to this component.  We use this in many of our products and need to have this resolve urgently. Is sending the affected samples to TI for evaluation a difficult process? So far it seems to be. Any suggestions?
