(1)
Tested with less than 5
effective series resistance and 100pF differential input capacitance. TA is the ambient temperature of the
TMP431/32. TDIODE is the temperature at the remote diode sensor.
(2)
Beta correction configuration set to
'1000' and sensor is GND collector-connected (PNP collector to ground).
(3)
Beta correction configuration set to
'0111' or sensor is diode-connected (base shorted to collector).
(4)
If beta correction is disabled (
'0111'), then up to 1k of series line resistance is cancelled; if beta correction is enabled ('1xxx'), up to
300
is cancelled.
