[sdiy] LM566 VCO

[Scott Gravenhorst]

I was once enamored with the LM566 until I found that it
was, at the time, unobtanium.  Now it's just expensivium.

Being a tri/square chip, I wonder if anyone can comment on
it's possible advantages over say, an LM13600 or LM13700
tri/square VCO with regard to range and linearity?

I've built an LM13600 VCO (from the data sheet) and found it
to be satisfactory with respect to linearity.  Since at
least LM13700 can still be found, what reason would one have
to spend $6.00 a pop for the LM566?  The LM13600 is also a
single chip solution, so I'm not clear on any advantage.

Thanks for input.
