DC Electrical Characteristics
The following specifications apply for V+ = +3.0 V
DC to +3.6 VDC, and all analog source impedance RS =50
unless other-
wise specified in the conditions. Boldface limits apply for LM41CIMT T
A =TJ =TMIN=0C to TMAX=85C; all other limits
T
A = +25C. 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.
