Note 13: This specification is provided only to indicate how often temperature data is updated. The LM92 can be read at any time without regard to conversion state
(and will yield last conversion result). If a conversion is in process it will be interrupted and restarted after the end of the read.
Note 14: For best accuracy, minimize output loading. 10k pull-ups resistors should be sufficient. Higher sink currents can affect sensor accuracy with internal
heating. This can cause an error of 0.64 ˚C at full rated sink current and saturation voltage based on junction-to-ambient thermal resistance.
Note 15: Hysteresis value adds to the T
subtracts from the T
discussion of the function of hysteresis refer to Section 1.1, TEMPERATURE COMPARISON, and Figure 3.
Note 16: Default values set at power up.
