Electrical Characteristics
(Notes 3, 6) (Continued)
Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits.
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 4: This initial current can be reduced by adding an appropriate resistor and capacitor to the heater circuit. See the performance characteristic graphs to
determine values.
Note 5: Do not wash the LM199 with its polysulfone thermal shield in TCE.
Note 6: A military data sheet is available for the LM199AH/833 and LM199AH-SMD (SMD#5962-88561) upon request.
