Hi,

 

In external ADC devices datasheet, there is a section which give some information such as conversion result accuracy with Fadc_clk relation or AVDD tolerance vs result error. but in S321xx datasheet, these information are not provided.

for example, if I use FIRC (1%) or SIRC(3%), what will be happened to ADC result accuracy?

 

Thanks.

Hello

 

Unfortunately we don't have that specific parameter. In this application note you can find the ADC specs and the best practices to increase accuracy https://www.nxp.com/docs/en/application-note/AN12217.pdf

 

Let me know if this is helpful, if you have more questions do not hesitate to ask me.

Best regards,

Omar
