(Note 6) Operating Ratings (Notes 1, 2) Temperature Range for Electrical Characteristics LM41CIMT (T MIN ≤T A ≤T MAX) 0˚C ≤ T A ≤ +85˚C Operating Temperature Range 0˚C ≤ T A ≤ +125˚C Remote Diode Temperature (T D) Range -5˚C ≤ T D ≤ +140˚C Supply Voltage Range (V+) +3.0 V to +3.6 V Analog Input Voltage Rage: +1.2V and +2.5V −0.05V to (V+ + 0.05V) +3.3V_SBY (V+) +3.0V to +3.6V +5V −0.05V to +6.67V +12V −0.05V to +16V DC Electrical Characteristics The following specifications apply for V+ = +3.0 V DC to +3.6 VDC, and all analog source impedance RS =50 Ω unless other- wise specified in the conditions. Boldface limits apply for LM41CIMT T A =TJ =TMIN=0˚C to TMAX=85˚C; all other limits T A = +25˚C. TA is the ambient temperature of the LM41; TJ is the junction temperature of the LM41; TD is the junction tem- perature of the remote thermal diode.
