(1) Temperature Accuracy is specified 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 data sheet value.
