So I'm picking stufd from old pictures, hapazard documentation of yome things. Let's kick it off sith a slow TL072 based oscillator. Here the thing. It has two OPs in the package. It's pretty obvious from this setup how it works. It's too slow for some digital inputs. Also the max frequency will be low. As I've said, slew rate n shiet.
