Description
The LM199/LM399 precision shunt reference features excellent temperature stability over a wide range of voltage, temperature and operating current conditions. A stabilizing heater is incorporated with the active Zener on a monolithic substrate which nearly eliminates changes in voltage with temperature. The subsurface Zener operates over a current range of 0.5m A to 10m A, and offers minimal noise and excellent long-term stability.
Ideal applications for the LM199/LM399 include digital voltmeters,...
