Part Number: ADS1255

Hi team.

I couldn't find The DNL parameter in ADS1255 datasheet?

So what's ADS1255 DNL is?

Thank you

Hi Mia,

In delta-sigma ADCs, the DNL is generally not specified. Since these ADCs have high resolution (often 24 bits), the noise is larger than the DNL value, which is typically very low. This is the case for the ADS1255, and why you do not see a DNL measurement in the datasheet.
