Forum Post: RE: ADS1292R: ADS1292R Data retrieval issues
Hi Anakshi, Thank you for your post. Can you recheck all power supplies and VCAPx voltages? Do you see the DRDYn signal toggling after power-on reset procedure is completed? You can find other helpful...

Hi Damian Hörner, See this post about the accuracy of the internal temp sensor, it seems to be more of a coarse measurement that is not trimmed initially. So it is possible the initial value is a few...

Hi Jean, So your program goes through addresses 0 to 128? It should definitely catch something then. I don't see anything wrong with your sequence either, which is unsurprising since you said it works...

Hello Jeff, Thank you for your post. You should try to route the P and N channel input traces differentially, but the total impedance does not need to be tightly controlled. The overall impedance...

Hi Machida-san, Thanks for sharing. Talking to the team, there is likely no intentional path between AGND and DGND, so it is difficult to measure. There may be some unintentional parasitic path...

Jason, No problem. I would note that if you have the EVM, you could test this with a little bit of modification to the board. Taking Channel A, you could remove the jumper at JP2, and then unsolder...
