Part Number: ADS1261EVM Hi. I was wandering if someone can give me some quick tips for using the ADS1261EVM . I'm not completely new to the concept of AD converters, but it's my first time actually using one and trying to get it to work. I have successfully installed the drivers, the support package and the Delta Sigma software and I have the board properly connected to my PC. I'm now trying to receive a signal and view the data in the software. But I only see static noise and no real values. I have a precision DC powersupply connected to ground to ground and I connected the positive wire to different connectors. I have the slight feeling that I'm doing something fundamentally wrong in how I connect my source. My questions: Do I have to wire the ground of my supply to the ground on the EVM? Does the software automatically detect which pin is connected and which isn't? Could the problem be that the EVM only measures differentially, and I need a reference signal to compare my supply voltage to`? I hope my questions aren't to silly and I've provided enough information but I couldn't find a post about how to properly set up the EVM. I've read through both the manuel for the EVM and the software but I couldn't find anything regarding connection a source. In the end I hope to connect something like a shunt or a thermal probe of some kind to build a small explample circuit. Greetings, Martin
