Hi,
After realizing using a 3.3v as a reference for the ADS1256 might be a problem, I'm trying to figure out how to connect the REF5025 and the ADS1256. I would appreciate any suggestion regarding the circuit design for connecting them.
Also, I was wondering how does the unstable 5v output of the RaspberryPi could be used to supply power to the analog ADS1256. I'm using it to convert the output of an accelerometer LIS344ALH which has a 33uv/sqrt(Hz).
Here is a schematics of what I have so far:
Cheers,
