Temperature-to-Digital Converter Characteristics
Unless otherwise noted, these specifications apply for V DD =+3.0Vdc to 3.6Vdc. Boldface limits apply for T A = T J =
T MIN ≤ T A ≤ T MAX ; all other limits T A = T J =+25°C, unless otherwise noted. T J is the junction temperature of the LM95241. T D is the
junction temperature of the remote thermal diod e.

Typical figures are at T A = 25°C and represent most likely parametric norms at the time of product characterization. The typical
specifications are not ensured.
Limits are specified to Texas Instruments' AOQL (Average Outgoing Quality Level).
Local temperature accuracy does not include the effects of self-heating. The rise in temperature due to self-heating is the product of the
internal power dissipation of the LM95241 and the thermal resistance. See Note 2 of the Operating Ratings table for the thermal
resistance to be used in the self-heating calculation.
The accuracy of the LM95241CIMM is ensured when using a typical thermal diode of an Intel processor on a 65 nm process or an
MMBT3904 diode-connected transistor, as selected in the Remote Diode Model Select register. See typical performance curve for
performance with Intel processor on a 90nm process.
This specification is provided only to indicate how often temperature data is updated. The LM95241 can be read at any time without
regard to conversion state (and will yield last conversion result).
Quiescent current will not increase substantially when the SMBus is active.
