DESCRIPTIO

FEATURES

■

6.95V Shunt Reference

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

overacurrentrangeof0.5mAto10mA,andoffersminimal

noise and excellent long-term stability.
