[sdiy] CA3046 vs. SSM2210

[pata at ieee.org]

Hi Kyle and the Lists!

CA3046
Status: Discontinued (DIP package).
Consists of 5 NPN TR's but 1 matched-pair.
Reasonable price ($0.5 or less)
Caution: Lots of FAKE are seen in market.


SSM2210
Status:Active
Consists of 2 NPN TR's as 1 matched-pair.
Lower noise, closed matching.

I recommend SSM2210 rather than CA3046 if you want to get better
characteristics, but we know CA3046 (or even CA3086) is good enough in
all circuits in analog synthesizers.

So, you can choose as you like.
