Original question:

ADC121S101-Q1: Non-Linearity information for 5V supply range

ADC121S101-Q1: Offset Error and Gain Error for 5V supply

Part Number: ADC121S101-Q1
Other Parts Discussed in Thread: ADC101S101, ADC121S101

Please inform Offset and Gain Error for 5V supply.

I could only find the values for 2.7V to 3.6V range in the datasheet (item 7.6).

Best Regards.

    Hello Edson,

    I will need to do some digging to see if there is any additional data that we can share for this device at 5V operation.

    There is a 10b version in this same family of devices that is specified at 5V operation for Offset and Gain errors, the ADC101S101. You could use this as a worst case estimate for the ADC121S101. For example, the typical offset error for the ADC101S101 is 0.1LSB. This would translate to 0.4LSB for the ADC121S101. If we do have data, I would expect the typical to be less than 0.4LSB, but this sets an upper boundary.

    Hello Keith

    Ok, Thank you.

    This helps but unfortunatelly I need the values for the ADC121S101. We are finalizing a Project and need the final values.

    Please inform it asap.

    Best Regards.

    Edson

    Hello Edson,

    I have not been able to find any additional data regarding this device. As of now, the only information we have is what is already in the datasheet.

    If I find anything else, I will reply to this post.

    Regards,
    Keith
