The LM185-2.5 is a two-terminal band gap reference  
diode that has been designed for applications which  
require precision performance with micropower opera-  
tion. The device provides guaranteed operation specifica-  
tions at currents as low as 20µA. The nominal voltage is  
2.5V with both 1% and 2% tolerances available. Some  
additional features are: maximum dynamic impedance of  
1, low noise and excellent stability over time and tem-  
perature. The advanced design, processing and testing  
techniques make Linear’s LM185-2.5 a superior choice  
over previous designs. A circuit for cold junction compen-  
sation of a thermocouple is shown below.
