Hi staff
We are evaluating a prototype board on which LMT70 is mounted.
I have a question about the output of the temperature sensor.
<Question content>
Install the prototype board on which LMT70 is mounted at room temperature (about 25℃).
A thermocouple is attached to the surface of the board near the temperature sensor,
and the output of each sensor (after temperature conversion) is compared.
The temperature of the LMT70 is about 3℃ lower than other temperature sensors.
(Temperature sensor input voltage 3.3V)
The temperature sensor is not in contact with other parts.
In addition, we do not perform resin molding.
Even if you raise the temperature, the temperature difference is the same.
Please give me a hint as to why it is 3 ℃ lower than other temperature sensors.
best regards
