Hi Miguel,
I 100% agree regarding endless discussion. About a week ago I posted a request for specific information on a specific function not documented in the datasheet. It would have been sufficient to say: "The request is denied". That would have saved us from going on this wild-goose chase after parasitic leprechauns.
If/when you have additional information or documentation on the specific subject, please post.
Best regards,
Snorlax
P.S. There is no mentioning of internal AFE in the datasheet. However in your and others’ writings the term AFE has been extensively used to describe analog circuits external to AD5933. Setting the context would be beneficial for the readers to understand which AFE it is.
