(1) Typicals are at T
A
= 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 V
DD
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.
