Hello everyone,
I am making a project with an ADS1256 module. In this project, I'm using a LM2596 module (converting 12V to 5V), an ESP32 module and a mux CD74HC4067 module (multiplexing other sinals).
I made a Breakout board with each single module, to test before to buy each component and build my own board with everything together.
It turns out that, when I power the ADS by the LM2596 (5V) it is burning its communication, making it DRDY stand in HIGH level and the VREFP shoting down it entry voltage to 1V (2.5V to 1V). But when I've tested my board, powering it by the ESP32 USB, it's working everything fine.
Any sugestions of why is it happing and how to correct it (if the ADS isn't burned)?
