Temperature-to-Digital Converter Electrical Characteristics (continued)

Unless otherwise noted, these specifications apply for VDD = +3.0Vdc to 3.6Vdc. Boldface limits apply for TA = TJ = TMIN ≤

TA ≤ TMAX; all other limits TA = TJ = +25°C, unless otherwise noted.

This specification is provided only to indicate how often temperature data is updated. The LM95214 can be read at any time without

regard to conversion state (and will yield last conversion result).

(6)

Quiescent current will not increase substantially with an SMBus communication.
