The differential ADC on my circuit has 1 channel open, and I decided that to place a temperature sensor IC. The temperature IC is LMT70. According to the output voltage table from the datasheet, the output voltage in relation to the temperature are:
My uncertainty comes from that the table shown is for a 2.7V supply, and I can only provide 3.0V (same as the ADC's supply.)
Would this table still hold true even for a 3.0V supply? The ADC uses an internal 1.2V reference and although that 1.2V on this table is -20 degrees Celsius a situation where my circuit will most likely not be exposed to im worried that the 1.2V Vtao of 3.0V supply would creep to the 20 degree Celsius where the circuit will be exposed to.
I would hope that I won't have to use a voltage divider to lower the output to not waste the accuracy of the IC.
