8.3.5 Fast Measurement Intervals With No Self-Heating Concerns

The TMP126-Q1 is optimized to minimize the effects of self-heating and maintain the temperature accuracy if the conversion period is greater than 31.25 ms in continuous conversion or one-shot mode. This eliminates measurement waiting time normally needed for self-heating avoidance.
