I am doing a demo of cn0338(gas measurement). I have an issue about how the adc works and what is the resolution rate or what is the af and fs constant mean. I am working on the readings of the measurements but I think they are not so accurate that is why I want to figure out the how the ADC works? Does anyone know video or document about configuration the adc. Thank you for your reply.
This page provides the link to the project that shows an example on how to interface the EVAL-CN0338-ARDZ with an EVAL-ADICUP360 which contains ADuCM360:
You can find an example of ADC setup method at:
Also this document explains in detail the operation of the ADuCM360 ADC modules at page 20 of 176:
Looking at page 41 of 176 we can see that SF stands for sinc3/sinc4 filter decimation factor and AF stands for averaging factor which are used together to get a wanted sample rate and signal filtering.
