APPLICATION NOTE 1057
Compensating for Ideality Factor and Series Resistance Differences
between Thermal-Sense Diodes


Abstract:When using an external thermal diode to measure temperature, the accuracy of the temperature measurement depends
on the characteristics of the external diode. Two critical parameters that affect measurement accuracy are ideality factor and
series resistance. This application note explains the effects of these parameters on remote temperature-sensor measurements
and discusses how to determine compensation factors for their
