Re: Some things I've learned about the FV-1
So, here is my feedback on FV1 and noise: - I have used juste one 3.3v supply on my PCB (REG113NA) - No noise at all when using a 5V power supply adapter to supply my op amps (OPA1642) - Noisy when using a 9V power supply adapter to supply my op amps (OPA1642) I have other issues but not related to...

Re: Some things I've learned about the FV-1
Thank you for the useful advices but i've a doubt about the separate power supply. What's the point of doing that knowing that there is no dedicated AGND and DGND on the FV1? The return current would be on a single ground plane. Usually we separate analog and digital ground but in the FV1 case,it's...
