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

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

(4)

Following a power on reset, the user must allow at least 228 ms before making the first read transaction to ensure a first valid

temperature read. After the first read, in order to ensure an accurate temperature result, the time interval between any two consecutive

temperature reads must be greater than the maximum conversion time of 228 ms.
