dual OTA circuits

[jessenator]

Curious about this

I'm tinkering with a couple of OTA circuits and it got me thinking:  anymore it's more economical to use the LM13700/NE5517 dual OTA chips, and just terminate one of them.

Wondering if there are circuits that can take advantage of both amps.

See if you can find a Ross phaser schematic. I can't remember if it does or not.

I'm working on a multi-band compressor that would use both sides of the LM13700, but I haven't had much luck getting it to work yet. Other than that, I can't think of any circuits that use both sides.

nope, sadly :/  thanks for the suggestion, though

edit: ope, my b, looks like this could be? Translation says LM13600 (slightly different spec, but basically LM13700)

Interesting. Yeah, keep us posted on that. sounds neato

Supposedly the top half of this circuit acts as a noise gate.
Could be useful in noisy fuzzes
