How to check a 12 bits ADC

[Acetronics2]

Hi, Flotul,

consider you have NO chance to get what you want with the internal ADC's of your Pic.

that said ... if you want a "quasi-linear " behaviour, try this inexpensive chip : https://fr.aliexpress.com/item/10050...Cquery_from%3A

But, of course, you'll have to be extra careful with all its environment ...

Hey Alain,

Thanks for the advice

What about the MCP3221 I have in my drawer? Is it worth a try or should I scrap them

I don't really know what to compare looking at ADCs.....
