Thanks Neil, I'll have to think some more on what you've written.

This is the crux of why I wanted to understand this more (rather than just build the datasheet design). I'd like to use this for a triangle-core oscillator. The obvious (I think) way to do it would be a have the sign of the input current into VCA2 alternating and feed the output straight to the integrator.

Cheers, Liam
