The only thing that bothers me is this is based on an IC that has been
in production for at least 9 yrs. It cousin the SSM2165 has been
obsoleted by the SSM2167. From ADI webpage I wonder how long the
SSM2166 will remian in production? The 14 pin dip version is obsolete.
Also for the SSM2166 the status column puts a contact ADI. It should
be either not reccomended for new designs, obsolete or in production.
I wonder if AD is considering obsoleting the part?

You're right about the DIP being obsolete. This is not an indicator
that the SO will also go that route. I checked with Analog Devices
before starting this project and they said there are no plans to
discontinue at this time. Now, that really doesn't mean anything...
but if they discontinue... they discontinue. My opinion is that this
will not happen for perhaps five years. By the way... the "check with
ADI" on their site has to do with availability at this time. It seems
that this chip is undergoing a fab location change... probably moving
to China (where else) and the location is not ready. The lead time for
this chip right now is 36-38 weeks. It's fortunate I have plenty to
get started... since brokers are getting upwards of $10 a piece for
these right now.
