Product Summary

The LM399H is a Precision Reference. The LM399H precision reference features excellent temperature stability over a wide range of voltage, 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. The applications of the LM399H include Precision voltage reference for multimeters, Calibration equipment voltage standards, Laboratory measurement equipment, Industrial monitor/control instruments and High accuracy data converters.
