zero point sdx,why a tl062?

[garfo]

Yeah, that's it.any particular/technical  reason for the use of a tl062 on the sdx zero point delay?

[Clayford]

Because it's a common, easily obtainable, often onhand part? It's audio characteristics aren't terrible, it makes a great buffer, and those of us that know a better part that could be used will if we desire?


Just speculation.

[garfo]

Well, why not another 072 then,it has better slew rate and much lower noise!?

[Scruffie]

Cause it's in the LFO, it has no effect on noise or the audio path and has better characteristics to function as a schmitt/comparator over a higher quality OpAmp, other options would be a LM358, 1458, TL022, all not great audio OpAmps but good for LFOs

Cool, thanks, that's what I was after.
