I need to replace a 5532A Chip in a audio preamp/mixer.
The original is a 5532A, which is also what the schematic has listed. This IC plugs into a socket, so I know I need the leads intended to go into holes on a PC board.
I looked at several online sources. There is a whole slew of 5532 chips with different suffix letters, but I have yet to find one with the "A" at the end.
Most seem to be 5532P. But I have seen the letters N and D, and some having multiple letters at the end.
All of them are listed as Dual Op Amps, and since they have the original numbers "5532" they should be interchangable (I'd assume).
What do these suffix letters mean, and why are there so many variations?
Is there some chart on a webpage that tells what each of these suffix letters mean? Can I use a 5532P to replace a 5532A? (Or any other suffixes).
