I'm trying to design a high voltage servo drive using the micromod teensy(and simplefoc) for general single and 3 phase power. I'm pretty good with digital signals but I'm a bit unsure how i should handle the adcs and the gate driver side.
I'm using allegro acs73002 sensors for current sense. They have pseudo-differential bipolar outputs and I'm trying to find suitable adcs and overall circuit how to handle them. Should I use single converters for both? A dual simultaneously sampling one?
I'm also wondering how big of a power source I need to power the motor side of things.
Here's what I've got so far:

Also other feedback is welcome.
