6.95V Shunt Reference
Guaranteed 0.5ppm/°C Temperature Coef?cient
Guaranteed 1 Ω Maximum Dynamic Impedance
Guaranteed 20μV RMS Maximum Noise
Guaranteed Initial Tolerance of 2%
Wide Operating Current Range
Available in 4-Lead TO-46 Metal Can
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
