Temperature-to-Digital Converter Characteristics (continued)

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

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 LM82 can be read at any time without regard

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