I am working on updating a design due to the fact that the LM4882 is now obsolete. I have decided to change the amplifier to the LM4880 which is basically the same as the LM4882 with the exception that it is Dual amplifier. For this design I will only need the first channel (IN A, OUT A). There is nothing mentioned in the datasheet on what to do with the second channel (IN B, OUT B) if not used. I do not want to just leave the input pin of channel B (Pin 6 - IN B) floating.
My question is how should I define pin 6 (IN B) on the LM4880 if it is not being used?
Thank you for your help.

Dave Callahan
