Temperature-to-Digital Converter Characteristics

Unless otherwise noted, these specifications apply for VDD = 3.3V . Boldface limits apply for TA = TJ = TMIN to TMAX; all

other limits TA = TJ = +25°C, unless otherwise noted.

Typicals are at TA = 25°C and represent most likely parametric norm.

(2)

Limits are guaranteed to TI's AOQL (Average Outgoing Quality Level).

(3)

The LM95071/LM95071-Q1 will operate properly over the VDD supply voltage range of 2.4V to 5.5V.

(4)

This specification is provided only to indicate how often temperature data is updated. The LM95071/LM95071-Q1 can be read at any

time without regard to conversion state (and will yield last conversion result). A conversion in progress will not be interrupted. The output

shift register will be updated at the completion of the read and a new conversion restarted.
