Dear All,
I was studying the C2000 Resolver to Digital Conversion Kit and I came across the attached schematic design. I am wondering if you can let me know if R30 and R34 are designed for one specific resolver in mind. If the answer is yes I would really appreciate if you can share any application note explaining how to design this based on resolver datasheet. I have seen some reference designs that don't use this loading resistor. I am thinking I may have to adjust the hardware of this circuit if I want to use different resolvers? Also, I am a bit concern since I would also be loading the "from resolver sine" signal and doing a full have rectification, then a differential to single-ended after that filtering and then analogue to digital conversion. I intend to use the circuit described above as a backup to calculate the velocity if needed.
Thank you in advance for your response.
Regards,
Alex
