[sdiy] One more part gone (SSM2210/SSM2220)

[George Hearn]

I use these in my VCO modules it's a shame, but there are always
replacements and it's a simple mod.  The linear systems LS318 is pin
compatible and would have similar performance, has anyone ever obtained any?
Further to that has anyone any experience with them?  The matched pair is so
important for synthesis projects for log converters, OTA's, current mirrors
etc. it's a shame to lose a good one.  George

Looking around the Analog Devices site, the pricing and availability  
for the SSM2210 has disappeared altogether. The SSM2220 looks like  
they're getting rid of the non-ROHS version, but the PZ lead-free  
version is still listed as "production". However, neither part  
appears on the Matched Transistors page. There's no comment there  
about the recent (?) disappearance of the SSM parts or the MAT02  
being obsoleted.

They have loads of links to their *new* parts, but I can't find  
details of the stuff they're making unavailable anywhere. How is  
anyone expected to find out about this? Grrr.

Looks like I'll be buying THAT300 series parts in future then.
