DESCRIPTIO
The LM199/LM399 precision shunt reference features
excellent temperature stability over a wide range of volt-
age, 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 0.5mA to 10mA, and offers minimal
noise and excellent long-term stability.
Ideal applications for the LM199/LM399 include digital volt-
meters, precision calibration equipment, current sources
and a variety of other precision low cost references. A 10V
buffered reference application is shown below.
