Hello fellows,
I have been looking into some analog synth modules, and no matter where I look the OTA seems to be the heart of every one of them. Or something equally important anyway.
As you are surely aware, the rediculously widespread CA3080 is now rediculously priced and out of production (since 2006 I believe?), and the only "alternative" that I know of is the 13700 and 13600 chips. Which is not an alternative at all, since those are dual OTAs, and 2 euros a piece is a considerable amount.
Which brings me to the big question, are there any general use, low cost and still in production OTAs? nothing fancy, just something to get the job done nice and easy. I'm looking for a price like 0.8 euros, not in huge quantities (something like 5 )
*I am shopping from the Bay, because the shipping fees from major electronics stores on the internet are pretty high and require big orders (I'm located in Greece). Even if there are a couple of stores remaining that won't drink your blood to give you a CA3080, the question of what to use in its place in the future remains.
Also, I'd welcome a few ideas of doing the same thing with normal opamps and transistors-just a rough guideline to tailor it to each circuit's needs.
Thanks a lot
