ADS1255: the input voltage

Part Number: ADS1255

Tool/software:

Hi team,

do we have specific value on the minimum input voltage so that we can have normal output and ignore the noise? thanks!

  • Hi Zoey Wu,

    The ADC noise is provided in the datasheet, see Table 1 to Table 6. These tables provide the noise level of the combined ADS1255 ADC + PGA, and defines the lowest level that the ADC can measure (assuming no other noise sources of course)
