Regarding to the temperature threshold accuracy on TMP709, I have some question.
(1)Can we program the TMP709 temperature threshold by an external 1% resistor at TA>0°C (less than 0°C)?
If so, could please tell me the resistor value at set point -20° C?
And about the operating temperature range (0°C >TA≥-40°C) in datasheet,
It means that it does not guarantee as the accuracy. My understanding is correct?
(2) How much threshold accuracy does it have from 0°C to 60°C?
(TA = +60°C to +100°C -> +-0.5°C typ, +-3°C max),
Will the accuracy become +-0.5 ° C (typ) in the range from 0 ° C to 125 ° C?
Or will we refer figure.4(TEMPERATURE ERROR vs TRIP TEMPERATURE) on page 5 in datasheet?
