Tested with less than 5-Ω effective series resistance and 100-pF differential input capacitance. TA is the ambient temperature of the

TMP411. TDIODE is the temperature at the remote diode sensor.

7.5 Electrical Characteristics

at TA = –40°C to +125°C and VS = 2.7 V to 5.5 V, over operating free-air temperature range (unless otherwise noted)
