Me degrade you...
Now that's a switch. You can dish it out but can't take it?
As for defending your degree... don't bother. It hard to defend

Brian there is one thing you have said that is true. It is hard to
defend what you don't have. Like Rhett Butler said to Chariolete,
Frankly I don't give a dam what you really know and what you think you
know.

Actually it would be interesting to see a schematic. Just looking at
the evaluation schematic and his photos on Ebay it is not just a copy
of the evaluation board. So he had to put some thought behind it. At
least give him credit for that. One thing is I am not going to pay
that price to see a schematic or reverse engineer it to see how it
works. Can do that from the specification.

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 The 14 pin dip version is obsolete.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?

He hacked the design from a page I cited several years ago while
criticizing his earlier splatter-box. The only thought he had was how
he could get away with the theft of someone else's intellectual
property. His solution was to withhold the schematic. I guess he
didn't realize that his amp could be reverse-engineered... duh!!!

Not for that price, for sure. But his latest hack? Yep! I'm going to
buy one and do a full -- and FAIR -- evaluation on my bench. I'm just
waiting for him to go into "full production".

I'm sure NTE will make replacements for ten times the original cost.

Which is one reason why I avoid ASICs.

Frank, you keep reminding us what a fantastic engineer you are... I
really don't know why you couldn't just draw the schematic from the
picture I have at http://www.telstar-electronics.com/d...evelopment.htm
You should be able to do that with your eyes closed... lol

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.

According to Digikey's webpage they have 320 in stock at $5.16 each
single unit quantity. Avnet and Arrow have no stock and on teh
SSM2166SZ they are quoting upwards to 16 week lead time.

Now that is a mor erealistic lead time. 36 to 38 weeks tells me that
the next production run of that IC is not scheduled for at least
another 10 weeks and curent production runs are spoken for. I would
say that this is not a super high run IC. Just enough though to keep
the line open and do a RoHS conversion to the packaging.
