DESCRIPTIO
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
1Ω, 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.
For applications requiring guaranteed temperature drift,
see the LT1034 data sheet.
