ADS8634: The deviation of Temperature drift

Part Number: ADS8634

Hi,

Temperature drift is specified 20 ppm/℃(typ).

How much is the deviation of this drift for our reference?

I don't require guaranteed.

Best Regards,

Kuramochi

  • Hello TQ,

    A typical specification often represents roughly one standard deviation of units or 68% of units. Therefore two standard deviations or 95% of units will fall within +/-40ppm/C and 99.7% of units will fall within +/-60ppm/C.

    Since there is not a maximum specification in the datasheet it is possible to receive outlier units that experience drifts that are larger than these estimates but the odds are pretty low.
