parameter values

Maryori Thank you for your question.  Mentioning dendalisay for assistance. 

Hi Maryori ,

I’ll move your query to the Precision DACs forum, where someone can better assist you.

Thanks and kind regards,

Hi Maryori ,

1. Offset Error Drift
-> The datasheet doesn't exactly provide the offset drift but if it can suffice your analysis, the Offset Error and Temperature coefficient are available.
2. Reference Temperature Coefficient
-> The LTC2621 only uses external reference so this spec will depend on the reference used.
3. The tolerance on the Vref of Vcc=5V
-> You can safely use Vref in this range: 0V ≤ VREF ≤ VCC. The tolerance will depend on the stability of the rail and reference used as both of these are external supplies.

Hope this helps.

Regards,
Flynn
