(1)
Tested with less than 5Ω effective series resistance and 100pF differential input capacitance. TA is the ambient temperature of the
TMP411. TDIODE is the temperature at the remote diode sensor.
(2)
When there is no remote diode connected, the first remote conversion must be ignored with the power supply ramp rate less than
240V/s.
