(1)

Temperature Accuracy guaranteed in both continuous conversion mode and one-shot mode with a conversion period greater than or

equal to 31.25 ms. Averaging on or Averaging off.

(2)

Repeatability is the ability to reproduce a reading when the measured temperature is applied consecutively, under the same conditions.

(3)

One-shot mode setup, 1 sample per minute for 24 hours.

(4)

Long-term drift is determined using accelerated operational life testing at a junction temperature of 150°C. Temperature Cycling and

Hysteresis effect is calculated out of final datasheet value.
