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.

ELECTRICAL CHARACTERISTICS
Note 4: Devices with maximum guaranteed long-term stability of
20ppm/√kH are available. Drift decreases with time.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 5: This initial current can be reduced by adding an appropriate
resistor and capacitor to the heater circuit. See the Typical Performance
Characteristics graphs to determine values.
Note 2: The substrate is electrically connected to the negative terminal
of the temperature stabilizer. The voltage that can be applied to either
terminal of the reference is 40V more positive or 0.1V more negative than
the substrate.
Note 6: Guaranteed by “Reverse Breakdown Change with Current.”
Note 3: These specifications apply for 30V applied to the temperature
stabilizer and –55°C ≤ T ≤ 125°C for the LM199; and 0°C ≤ T ≤ 70°C for
A

the LM399.
