ADS54J54: ADC codes not measuring as expected

Part Number: ADS54J54

Hi Attachment has questionWe.docx

  • Ajayt,

    We are looking into this. There was an error with the offset error you mention from the data sheet. This should be +/- 25 LSB's, not 25 LSB's.

    Regards,

    Jim

  • Ajayt,

    The +/-1.91mV of offset error is a TYP spec measured on a low number of units. I am trying to collect ATE data to see if the results are more in-line on what you are measuring.

  • Ajayt,

    We have reviewed some recent lot data.  We did note an acceptable mean shift in the distribution of offset error compared to our initial results.  A significant portion of the measurement distribution still falls within the stated range of our typical spec.

    Please note that typical specs, including +/- typical are not a guaranteed specification

    Regards,
