I haven't looked for them yet - found a Phillips data sheet that said hey
were discontinued, so assumed they might be hard to find.


Could be that refers to an 'N' suffix.

Somewhat strangely it seems that Philips *have* discontinued it !

TI and JRC still make them I'm sure - and the 5532 as well.

I've sourced some 5532s with an A-something(P?) suffix, which apparently
means they have a guaranteed noise spec.
